Hi everyone !
Sorry, i know this problem has been already posted, but I've tried every solutions told, none succeed...

Let me explain :

I have the 5th years anniversary edition of Oblivion, and everything was perfect before i uninstalled Corel VideoStudio Pro... Now after the loading screen i have a freeze and Windows asks me something about "PureHD", a software I didn't even know, and i cannot play the game...

I tried to fix it in registry but it didn't work :/

I run on Windows Seven

I hope someone might help me...
