Windows 7 permissions screwed up after installing game, (Might have be

[wombinator04]

I downloaded Black Prophecy beta client, installed it. During the install, It was installing microsoft .net framework and direct x stuff. I'm thinking that the framework did something to my permissions because I can't even launch the game. Whenever I try to launch the game it shows the "windows can't acess this file blah blah blah" crap. Now the reason why I think the framework screwed up my permissions is, now whenever I start up firefox, an error message pops and and says "microsoft and acess this file blahblabhl" Also I can't even uninstall the game, I have to manually drag to to the recycle bin. How do I fix this? Also I have FULL CONTROL on every file on the hard drive. And I'm the system admin.

Update, Now I can't even reinstall the game itself after deleting it.
