I installed the game correctly but when I start it I can only see a black screen.
If I move the mouse, I can hear the sound of the pointer hitting the menu options.
I tried changing the resolution manually inside the configuration files but it doesn't work.

Win 7
GeForce GT 525M on latest drivers
Intel core i72630QM

thanks!
