When I start it up all I get is a black screen with a with square in the top left portion. I couldn't find anything about this problem so I figured I'd ask you guys.

@creepyunclebrad:

Based on the googling I did other people are having the same issue but I didn't see any solutions.

Here's a few general Steam troubleshooting steps you can take:

• Restart your computer. (Sounds dumb, but just do it.)
• Validate the game's files: Right click game > Properties > Local Files > Validate integrity...
• Try hitting Alt+Enter to try to force fullscreen. I have no idea if this will help but since you're getting something after launching the game, maybe it's a display issue.
• if you want to be thorough, try either upgrading or rolling back your graphics drivers. It's impossible to tell which of these will work (if at all) unfortunately.

Good luck!
