After game (Only) Maestro Error.

Ive been playing league since beta on many different computers. I have never seen this before. 90% of the time when a game ends and i go back to the results screen. League generates and error that it can't connect to Maestro and the client will now ext. Its quite frustrating having to restart the game after almost every single game. I also cant talk to people after. Or check stat details etc.
