Logging in and Playing is not a Problem, but when i get disconnected by a rebooting Server or try to log out for any Reason, the Client happens to produce a Crash down to the Server Choice Menu without any Interaction Possibility, so i have to close it via Task-Manager... or it gets stuck to a blank Screen (white, blue, or black yet showed up), so i sometimes have to reboot my entire System to be able to play further on again.
