try to join any of the servers it says failed to verify username. i recently changed it from FuzzyLeo to Fuzzy_Ghost and will soon change it back (about 14 days) if there is no solution because im changing it soon its fine. i just wanted to play on it :I

I can think of 3 solutions but no idea if they work:

1. Try to logout and login on your minecraft launcher.

2. Try to logout and login on the dalek mod main menu (Top right corner with a gray button). 

3. Contact support@swdteam.com 

thanks. the second one worked XD i forgot about that

Nice
