Dang, still not working, really laggy at the start up screen and won't even go past the loading screen anymore without freezing and going into Not responding. I guess my card can't support it?
Exactly, your card cannot run the game. You need to upgrade your graphics card.
Damn, alright, thanks for the help anyway. I thought it would work since the demo worked just fine. I doubt they offer refunds, huh?
Jens knows about these things...
Another thing you could try is set the resolution at its lowest (640x480) and set all graphics options to their minimum. If it runs any faster, it means your card is really too slow (or maybe doesn't have enough memory).
I have a GeForce 7800GS and can't play it at 1024x768 (the resolution you tried it at).
