How to recover the relationship tools

I have version 4.0.3 of the sql developer and I'm trying to get the tools of the relationship. By creating an ERD it are not "green arrows" or something like that where other tools are.

Above two files are zip that I downloaded and extracted.

OK so I downloaded the version 4.0.3 Developer SQL 64 bit with JDK 7.

Extract the file to my C drive and run the sqldeveloper.exe file.

And for some reason that everything is how its supposed to be now. Don't know what the devil was wrong before...
