Currently there is a problem with our Launcher. The main difference is that the “old” launcher is able to patch the game files but can not connect to the game server. The new launcher is able to connect to the game server but not able to patch the game files even with admin mode enabled.
Best solution is to install the old launcher first and run it in admin mode. Let it patch your local files. Then install the new launcher and connect to the game server.
The buttons and login form shown in the new launcher are not fully functional so simply use the old fashioned ingame login process.
