I have seen one subject alike to this bug, but they have yet to solve the problem. I was wondering if there is another way to fix it. I have upgraded my video cards, tried opening it SLI I think it is called, but nothing seems to work. I had this game before it was greenlight and it worked just fine, but on steam is won't open and I am getting the Input Not Supported sigh floating across my screen, is there any other way I can fix this?

Also I tried launching it on steam in windowed, and different resolution through the properties tab. 

Need help ASAP so I can start playing again.

Thank you, Gota.
