I just bought BloodRayne2 and the game looks awesome...from the box

I installed and all it would do when I clicked the desktop icon was show the hourglass for a minute and then nothing...except leave "rayne2" running in the back ground taking up 98% of my processor. I uninstalled and reinstalled, no go. I tried omega drivers, no go. I tried the modded catalyst with the desktop drivers for ATI's Radeon 9100 AGP. no go. About this time I read the readme, lol, and it said my card was not supported...is there anyhrting I can do to play it? Short of buying another computer? I have searched and downloaded software for the last two days with no luck.
I have a Compaq Laptop Presario R3230US
