We need system specs.

OK.

Did you look through the link I provided?
Did you try any of them?
Did you check to see if your system meets the minimum system requirements?

All of these and more are in that link.

Let me know.

I Downloaded the xdirect file... and checked with my graphic card all was ok there... My system is high over the minimum system requirements for this game... thats the thing thats really bottering me.. it worked really good with vista...

Well maybe the DirectX update will help.

Keep us informed.
