Game crashes after selecting channel/ server pls help

Whenever I select a channel to play in my game freezes and crashes. If someone knows a workaround it would be greatly appreciated.

EDIT: Might be because of server restart
EDIT: Can't launch anymore Just comes up with server updating please standby. I checked and the server is up. But still won't work

 

I've never heard of this before, maybe try re-downloading the game and see if that helps with anything. The first time I installed this game, it would fail to launch and I had to re-install.

 

its says "The Account Authentication Key has Expired" right?
