Friend's Q menu won't open. . . .

My friend tried to play Multiplayer with me, and his Q menu wouldn’t open. He went to singleplayer, but it wouldn’t open there either. The only thing he did (since the last time he opened it) was play Dark RP. I was just wondering how I could help him out.


Can you please be helpful? Thank you.

I said something stupid thats why I snipped.

did he bind it to something else? try going to options -> keyboard -> default
