I've installed it and patched it to v1.01 and i keep getting an error crash when i run it

It goes through the normal procedure when loading- the opening credits appear but then i get a blank screen just black and when i press enter in the left corner i get something saying escape key

i've tried to install this again and i'm stumped as what to do

any suggestions from the great yonder

if it helps my spec is

abit IP-35 pro
2gb crucial ballistix ram
500gb sata seagate hard drive
antec truepower quattro 850W
tuniq tower cpu cooler
asus dvd rom
asus dvd writer lightscribe
windows xp pro service pack 3 32-bit
intel Q6600 SLACR overclocked to 3.0ghz
bfg 8800GTX OC (don't know if it matters but i'm still on the same drivers for this as i had last xmas when i had the card)

Thanks to anyone who can shed some light on this
