Try as I might, Gex will not launch on my system. I hear "Party Time!" and see a tiny window, but the game doesn't actually launch, nor can I click any of the menu items on the launcher. Suggestions?

Same thing happens to me as well. I still can't find a solution.

You might try messing with "Compatibility" options, but if that doesn't work, contact Support for sure.

That's weird, my PC is on Windows 8.1 but it's running just fine.
