I'm not sure of the cause of your problem, but re-installing is the only fix or this to my knowledge.
Maybe try just installing again, without uninstalling the game. That's helped me. but if you uninstall, I don't think it gets rid of any of your files. If you wanna be safe about it, though, move all of your maps and/or presets to a separate folder, then move them back once you finish reinstalling :3
