It occurs after and on 2 different computers. Only installed the Shark windows 7 codecs on one computer. Uninstalled it and even tried system restores but nothing is helping
Did you restart the computer? Did you do upgrade installs for both of them? Sometimes everything doesn't work properly when you've done an upgrade install instead of clean installs. You might try a http://www.sevenforums.com/tutorials/3413-repair-install.html?ltr=R. It may fix certain problems, other than that, I don't know what to suggest.
Repair install didn't solve the problem. I did a clean install again and its working again. Seems the problem was Sharks Windows 7 codecs. Thanks for the tips.
