Ever since downloading Old World Blues and the patch with it, every time I load my game up I have no mouse whatsoever. I can use the keyboard to load my game but still no mouse. If I pull up my steam overlay in game my mouse appears, but doesn't work for the game. I disabled every add on I have including all 3 DLC's and still nothing. Completely uninstalled and reinstalled. I verified the game cache and every time it says something is wrong and will redownload but even if I run it as soon as its done it finds another issue. I reinstalled my mouse drivers for my Razer Naga and just everything I can think of
