Hi everyone. I'll really appreciate if some1 will respond to this. I have some serious problems with controls of the game. At first, when i've just started the game everything seems alright, but when i fail and retry - i sometimes cant use melee or switch firemode, sometimes i even cant shoot! i have wire mouse and keyboard, movement controls are working properly, no error msgs\ background programs are running during this crap. plz help =((

I've found problems with melee, Stealth Kills and grabs at times.
