Grenade launcher

[Medication]

I have a specialist in a second window, when ever i equip grenade launcher for a first time my main account and sometimes specialits it self get kick out of game with no error( game windows just closes) . After relog you can use it normally, but as soon you switch weapon and equip grenade launcher again same thing happens. No error in net log either.
