I too had a problem when I first installed the demo. I couldn't set the
textures to 32-bit or whatever that option is. It run for 3 or 4 seconds,
teh screen would corrupt, I'd get some sort of error message (not sure
exactly what it said), then I would drop back to the desktop.
Unfortunately, the desktop was so bright I had to reboot to fix it. Nothing
else worked.
I had recently reinstalled WinXP because of a boneheaded thing I did. This
reinstall occured before installing the demo. For some reason, when I
reinstalled the OS, it ran a bit sluggish for some reason. Windows would
take a while to pop open and such. I own an AMD VIA system. I uninstalled
the VIA drivers and installed them again. Then, 3.7 Cat's came out. I
updated the system to them. Not sure which fixed the problem, but all
things seem to be fine now with the demo.
Moral of the story: you sure you got all the latest drivers and such
installed?
Good luck!
