What is going on with Attack of the B-Team?

Ok, I'm sure everyone knows how you make a single player world and then you log off. Then the next time you get on, you can't play that world. But now, I can't even make a new world. When I make it, it goes to the escape key and makes me go into that menu and then shuts down the server. When can I expect a fix for this?
