[Crash] Game tells me to reconnect without success

When i start the client the client tells me "the game crashed" and i can click the reconnect button, once i do so i have a blackscreen for 1-2 minutes and then i get an error message (error occured, cant connect) and i am back to the screen that asks me to reconnect. Its been like this for 3 hours now, i tried everything, even completely rebooted etc. What should I do now?
