Same problem here with my brother's username. It's my own server, so I think things are good on that side. I can log on with my username. All my friends can log on with their usernames. But my brother gets the black screen > flash > white screen issue. Here is my log: [14:23:07] [sEVERE]------------------------------------------ [14:23:07] [sEVERE]Launcher is starting....
