my mouse and keyboard=dead

[sirIFK]

everytime im in a game, right when it starts, the mouse and keyboard die. I cant play because i cant move mouse. i works before, but during game its dead. it just sits in middle of screen, while i need to choose a map. i dont know what to do, i tried restarting my computer and alot of basic resolutions and nothing happens. it started about 2 hours ago, and i cant fix it

This happened to me also. Check your key bindings. There's another post here somewhere talking about this issue, I'm just too lazy to find it right now.

It seems that something causes the game to lose your key bindings sometimes. All I did was reset all bindings to default, then make changes from there.
