Repeated crashing.

Right after champion select, the loading screen didn't launch, it was just a black screen, I tried restarting LoL a couple of times, but I didn't get anything until the game was over, the message was "unable to connect to server, please check your connection and attempt to reconnect to game." I think. I'm also hoping you might be able to forgive the loss for my teammates, however that might be a bit of a stretch.

Edit: Just launched a custom game, and it seemed to work fine.
