Adobe Acrobat seems to be frozen

I have problems with Adobe Acrobat Reader DC. It was working fine until yesterday, when it seems to seize up - I can't open to read PDF files at all.

  • When I double-click the icon in the apps folder, a popup box informs me that the app "is not open more" (this, even if in the dock, the small black dot appears next to the drive icon, which normally indicates an application is open).
  • However, if I try to drag the drive icon to the trash, I learned from a second box of pop - up that the app "cannot be moved to the Trash because it is open."

-J' stop force does not work, no matter how I try:

  • When I click and hold the icon in the dock and the dialog, I select the force quit, but nothing happens.
  • When I go to force quit menu Apple and select Acrobat and click on leave force to it, nothing happens.

At this point, I just want to remove it so that I can re-install the app and be able to read my PDF files even once.

I'm under El Capitan (towards 10.11.3) on a MacBook Pro. Thanks in advance for your suggestions!

In case it helps, that's what I got when I ran EtreCheck (associate down to protect certain personal information):
