I've tried to star the game now for some time, but every time the game loads the main menu and after a second or two the game pushes me back to the desktop with the game still running (though frozen) in the background. I have to open the Task Manager to close Olwin.exe.

I've tested it with the D3D and nGlide, but both freeze. I could get the game to run on software mode, but the game doesn't allow me to use mouse look and doesn't play in fullscreen.

Is there any solution to this?
