[CRASH] Dialog "Reconnect" without a game

I wanted to start a ranked game. In the primary/secondary-role dialog I couldn't choose anything. So I decide to restart the client. Now I get the "Game Crash / Reconnect" Dialog, but of of curse there is no game and after some seconds I got the default "check your connection" message.

UPDATE: If you stubborn trying to relaunch, you will have success. :)
