GTR Demo v2 crashes..

Hi all,

i've downloaded and installed the V2 Demo of GTR but when i try to start it,
the screen just goes black for a second. Then i get thrown back to desktop
and get a message that says that the "spa" directory already exists and asks
if i want to overwrite all files. No matter what i click on, the next thing
that happens is that windows tells me "GTRdemo.exe has encountered a problem
and will be terminated". And that's it then. Don't even get to the in-game
menus let alone on a track.

machine:
Athlon XP3000+
nvidia FX5200 Ultra
768 MB RAM
Win XP pro SP1

forceware 77.77
DX 9.0c




any hints?

TIA
