Garry's Mod Keeps Exiting!

Hey guys, I have been playing “PERP Roleplay on rp_evocity_v2”. I have been playing it for a while (1 day of total gameplay) but, recently, the game keeps exiting. I don’t mean the game crashes and turns off, it just leaves the game and ends up at my Desktop Background with all of the icons, ect. ect. I would really like you guys to help me as this server KICKS ASS.

Thanks, Pants.

Could someone have rebound your keys to exit? Silly but it can happen.

So are you saying rebind my keys to default?
