Serious Sam 2 startup problem 2 replies

ok. when i double click the serious sam 2 icon, an error message pops up saying:

Fatal error: Cannot set display mode! GfxAPI error: (Direct3D) Cannot create rendering device.

i have an ATI Radeon xpress 200 series built into my motherboard but when i first bought my computer from best buy serious sam 2 was working and then i formatted it. after i formatted it, i tried installing serious sam 2 and it doesnt work. i think that when i formatted my computer, it took things off of it that were installed when i got it from best buy. so maybe if u guys could suggest some downloads i could get, then it may work. please help.

Did you but it, download it, or get it free in a video card box?

Maybe it's just me, but can that card even run the game?
