I am at my wits end.

Everytime I try to run Demon stone I get to the loading screen and the little red ball fills up and nothing happens. Its like it freezes.

I have the latest patch. All drivers updated to latest version.
Windows XP Professional x64
Intel Pentium EE 965
Nvidia Geforce 7900 GTX
4GB of RAM
onboard sound

Plz help me get this game running

Unfortunately there's a lot of unresolved issues with getting the game to run, I hear... you might want to check with the official forums, though I've seen the same kind of problems and no solutions posted there.

You have a NVIDIA graphics card. The game will be unplayable, even if you can get it started.
