Where are you guys running the game from?
originally the desktop, tried it from documents a second time but i'm having the same problem.
Does the base folder exist?
yes.
Also what operating system are you guys using?
windows 7.
specific problem: i set my name to FancyPants, keep the server name the same, set players to 1, and select Single Player. the first time i press Start Server, it freezes momentarily, and the music cuts off. after about five seconds the screen resumes, but i'm still looking at my server settings, and any times i press the Start Server button again, it simply does nothing. also, the console that opens up never actually displays text for me, not sure where fastlex got that information from.
