crush after finishing the game; can't play any more

won the game, and then I was waiting for the post-game screen. waited for a couple of minutes and noting happen. I closed the game and logged in again, but then the "reconnect to the game" screen appeared. pressed reconnect, but it gave me a blue screen and nothing happen again. tried this a couple of times but nothing changed; now I can't play at all. it is waiting for me to get back into the game, but the game is over. and it doesn't "reconnect" either; it just stops me from playing any further.
