Just downloaded this game to desktop. Wanted to start it, it says it's launching, but NOTHING happens.

Any suggestions? I have a windows 7, 64 bit system, with GeForce GT650 M card, and 8 GB ram.

Thank you in advance!

Let's run through the basics first.
Do you have DirectX 9 installed?
Have you tried to reinstall the game, just to make sure it isn't some corrupted file?
Does the game work if you enter as admin but not as a limited user?

I'll think more tests later, but those should be a start.
