Doesn't quite work for me, I get this screen when running.
Windows 8.1, 64-bit
Does this happen the first time you play the game, or on subsequent boot-ups? Are you able to get past the main menu? Also, can you try going to C:\Users(your name)\AppData\LocalLow\Streets of Rogue\Streets of Rogue and delete GameSettings.dat. AppData is a hidden folder, but it will work if you type it into the address bar.
