I have just got the game and installed it (meanwhile 2 times).
After starting the game, it gets to the main menu where I can chose to go to "Options" "New Game" "Credits" etc.
I can move the mouse coursor but not click on anything. So it has the effect I cannot play.
My System:
Win 7 Home Prof (64Bit)
GTX285
Razer Lachesis
Maybe I have to mention that after the first start it had worked. I chose XBox 360 Controller as input ... and since then nothing works.
Maybe its been set into registry because either erasing the input config file nor reinstallation helped.
