Many people who play games that use GameGuard as an anti-cheating system know that Windows 7 has issues that cause it to crash.

There is a fix though, its quite simple. GameGuard has updated their software to work with Windows 7, but chances are your game hasn't updated the GameGuard software because they feel its not important.

Download the attachment, and replace the GameGuard.des in your game's MAIN folder, NOT in the game's GameGuard folder.

Launch the game normally, play , and pwn.

works on both 32 and 64 bit!

----------------------EDIT
alright seems to be a 50/50 thing, try it, hopefully it works. if not, google should be able to help.
