I've encountered this problem before. My game won't launch. Upon double clicking the icon or running the game via Steam, the splash screen pops up showing the version number as it loads. The game then minimizes to the start bar. Clicking on it to maximize it allows me to hear the first part of the intro before minimizing again. Repeating the maximization results in the same thing.

I've had this issue in the past and the only solution I found for it was to completely uninstall the game and reinstall it.
