In the last day or two, I've had to reset all of my mouse/keyboard buttons each time I load the game. On top of that, the game will stutter and freeze to a point that I have to restart my computer. Any thoughts?
Been playing or a few years now, but have never run into anything like this. Haven't used any mods, but I have been adding a lot of mods to another game; could that affect L4D2 in some strange way?
