I have had this 2 times now, and I don't play that much. sometimes the game gets stuch after the lauch countdown. Exiting the client and restarting makes me able to reconnect but the game won't load and then I have to close the proces with ctlr-alt-tab
If you ever used any mods try to run it without them. You can as well try to rename/remove mods directory completely just to be sure nothing remain there.
