Client thinks i'm still in my last game so i can't play a new game :/

Me and my mate were duoing and after the game we both couldn't play another game. When you press find match nothing happens, and every time i re log back in it thinks I'm in my previous game which is not there anymore. So basically the client thinks I'm still in my last game so i can't play a new game. Any thoughts? its not my client its my account because my other account works perfectly fine.
