Okay, here's a detailed explanation of your error:
Your computer has been raped by CrossFire's chooby version of Hackshield.
This doesn't have to do with hacking, but it does have to do with Crossfire.
I recently downloaded Crossfire, and whenever gameguard finishes loading, I get a blue screen of death.
I'm using Windows 7 RC 7277.
If anyone has found a fix for the gameguard crash, please let me know.
GameGuard does not yet support Windows 7.
Wait a few more months.
Just dual boot XP/Vista with Windows 7.
