I downloaded the game via Steam. I'm running Windows 7 64-bit. My PC exceeds the minimum specs, but does not lauch.

It goes through the activation process, but then does nothing.

Please help!

I have the same problem. The way I get it to launch is reboot, then launch the game from the Windows game folder icon. That works.

However, I have to do this every time I play the game. It goes through activation -- every time. Then it will not launch. I reboot. It then works.

Every time!

I'm going to post this separately as well. It is good to know that others are having the same problem.
