Wow Mem, that's kinda strange, you could play the game fine on Vista? I wonder why your vista was fine and mine was messed up. I don't get it, now i'm not entirely sure what the issue is. Thought i might need a new hard drive and OS but you've just proven basically that its probably not my OS. But i'm wondering if not all OS's are created equal. I mean one persons vista may work fine while anothers does not.
