I get the error message "a license is required to play the selected song or video. However, a license for this file is not found, has expired or has been altered"while trying to play a downloaded song

Original title: Media Player

Yesterday, I downloaded a song.  Now my Windows Media Player will not play anything.

I get the same room whenever I try to start each song in my library:

Media usage rights acquisition

wmasf.MusicNet.com

A license is required to play the selected song or video.  However, a license for this file is not found, has expired or has been altered.  To obtain a license for this content, please visit the website or open the software application in which the file was uploaded originally.  You need to connect or buy the song or the video.

I ran several diagnostic, and remedial programs, but nothing worked to get media player to work (without getting this popup Media Player and stop).

It seems to be a kind of malware that has damaged something in my windows media player.  When I put "wmasf.musicnet.com" in the address line on explore, I get only the same message as the pop-up.

Anyone know how I can fix the media player and get rid of this problem?

Hello

I would suggest trying the following methods and check if it helps.

Method 1:

Run the troubleshooters in Windows Media Player and check if it helps.

Open the troubleshooting Windows Media Player settings Troubleshooter: http://windows.microsoft.com/en-US/windows7/Open-the-Windows-Media-Player-Settings-troubleshooter

Open the troubleshooter in the Windows Media Player library:

http://Windows.Microsoft.com/en-us/Windows7/open-the-Windows-Media-Player-library-Troubleshooter

Method 2:

Try to reset the management of digital rights (DRM) and check if it helps.

Follow the steps to reset the DRM:

1. first of all, check that the hidden files and folders option is enabled.
To do this, follow these steps:

a. start Windows Explorer. To do this, click Start, type userinit.exe in the Search box and press ENTER.

b. click on organize, and then click folder and Search Options.

c. click on the view tab.

d. click Advanced settings.

e. under hidden files and folders, click Show files and folders, clear the Hide protected operating system files (recommended) box and then click OK.

2. Locate the DRM folder on the computer.
In general, the DRM folder is located in the following location.
Note In these paths, drive represents the drive on which Windows is installed.
Windows 7 or Windows Vista.

a. Windows 7 or Windows Vista versions x 86-based
drive: \ProgramData\Microsoft\Windows\DRM

b. Windows 7 or Windows Vista versions x 64-based
drive: \ProgramData\Microsoft\Windows\DRM

3 Rename the file DRM DRMbackup.

a. right click on the DRM folder and then click Rename.

b. type DRMbackup, and then press ENTER.

c. close Windows Explorer.

Warning: You must contact any third-party stores where you purchased music to reset the licenses for that music. If you copied CDs for protected Windows Media Audio files, the CD must be copied again.

  • CS4 components stopped working. Error 150:30 - license for this product has stopped working. How can I fix it?

    Last week, I had to wipe my hard drive, reinstalling OS X 10.10.4 (then update to 10.10.5) and restore all my files. I do not often use the CS4 but I needed to open Dreamweaver CS4 just now and all first, he wanted Java Runtime 6 - that I found and installed. Now I get the 150:30 error message: a license for this product has stopped working. I have the SN of the project - it is registered. But I can not get Dreamweaver or Photoshop (or any what other applications in the package, I guess) to run. What should I do to remedy this? As I said, I do not often use CS4, but sometimes I have to get to some old files using Dreamweaver and Photoshop. So, I want to make it work.

  • OPM get a "this file is not found error" but the document opens without plugin

    I'm under 64-bit Windows 7, Word 2010, OP 10.4.4.21.

    The scenario is strange.  Everything has been fine until today.  Something has changed, and now I am unable to open all the OPM Word documents (or compile compile all).  When I try, the error message ' Oracle Policy Modeling could not open document, such that an error has occurred in Microsoft Word: this file was not found ".". "  The document opens, however, but the plugin is not displayed.  I tried to reinstall OPM several times without success.  Indeed, during install it first a couple I'd always get the error message, but CERTAIN documents open with the active plugin and I could compile in the document - and some wouldn't have the plugin.  After another reinstall, OPM still throws the error, and documents open always in the background, but without the plugin active or exposed.

    I also tried to Repair Word, but do not want to reinstall office.   Excel seems to work very well.  I don't really know what was the triggering event.  The project has been using subversion when he arrived, but now all the projects on my machine, subversion or not, are concerned.  I think it's just my machine and others do not see this problem.

    Has anyone seen this?  Something corrupt?  It's almost like the word invocation simply does not work properly.

    Help!

    Thank you very much.

    OH - I found and fixed it.  Word has disabled the "Add-in".

    1. Click the File tab, click options.  A popup options will appear and then click Add-Ins.
    2. In the box macros complementary , if you see that policy modeling Word 2010 Template.dotm is disabled, you will need to enable it.  Downstairs, choose from the menu drop-down handle and click on the button 'Go '.
    3. Select the type of "Disabled" in the Management area, and then click OK.
    4. Select the item to activate, and then click the button 'Activate'.


    It was something that should have been easy.  We have a couple of experts of the Oracle takeover bid on the site and they didn't, and R & D in Australia has yet to respond to us.

  • Get the message: this program has been deleted while trying to open Windows Media Center

    Original title: I used to have Windows Media Center... But no more?

    I'm trying to connect with my XBOX 360, and it said to open Windows Media Center.  I clicked on start, then went to where Windows Media Center has been. I clicked on that and it says "this program has been removed."  Huh!  Is there anyway that I can download the program, or something?  Or is it IN the Windows during the programming?  Info/comments will be greatly appreciated.  Thank you!

    Brock

    You could try to control Windows Media Center via Control Panel / programs and features / Turn Windows Features on or off / multimedia / Windows Media Center, make sure that it is checked.

    System Restore will not uninstall or reinstall your entire operating system, take your machine over time until the selected restore point (you choose) and load Windows from this date and time.  Programs and updates that have been installed since that date and time are no longer available and need to be reinstalled.  System Restore will also leave you a "Undo" restore point which allows you to return to the present before the start of any restoration.  It also gives you an option to check what effect the return to a previous era will have on your program installed, etc..  It does not affect your personal data, applies only the settings, system files, programs, drivers, and updates.

  • I can't open some documents that I get an error message "error when opening this document. This file is not found. "

    Help please!

    I get the same message for lots of PDF documents, I have Acrobat Reader DC and some documents were created by me using this software.  I store it on our server and then I can not re - open them.  This also applies if I receive an email with a PDF attachment.

    Please help if you can?

    Use Windows Explorer. IGNORE THE RECENT FILES LIST.

    Is the PDF file WHERE YOU PUT it? (Did you choose where to put it?)

    If it's gone, you have a serious problem, but it is not due to lack of player if the file has disappeared.

  • After the last update, I can search is more for nothing. Any idea what has been disabled?

    I recently did a refresh on Firefox and now I can't use the search feature. I restarted in safe mode, I disabled all extensions, and I still have this problem. How can I fix?

    You can check if you have the XML files including Google's default search engine in the browser\searchplugins file in the Firefox program folder.

    If this isn't the case, then you need to reinstall Firefox.

    Try to delete the file search.json and possible search - metadata.json and search.sqlite files in the profile folder of Firefox to reset the default search engines.

    You can use this button to go to the Firefox profile folder currently in use:

    Firefox will rebuild the file search.json from the default search engines in the folder "browser\searchplugins" in the Firefox program folder and the searchplugins folder in the Firefox profile folder.
