Could you try to remove all files starting with "sr-" in the subdirectory base\pak\ ? It's possible that there have been some recent changes which were only supposed to be valid for the test server but became active on the live system. Maybe these files cause a kind of crash on your systems. If this doesn't help, try to remove/backup the config.json file locates in your Documents\BattleForge directory. Let me know if this helped you guys.
