Fatal Error - please help

Hey all I just downloaded the Hitman 2 demo and I want to play it but I get a fatal error every time I try to start the game. I’m running Windows XP, ATI Radeon 9000 Pro, dual monitors. I downloaded the latest drivers for my video card but that didn’t do anything. The error simply says “Open GL : SelectPixelFormat failed. Hardware accelerated not supported.” I have a screenshot of the image but first how do i enable html?
