Same thing is happening to me. I just open it and really quickly click something other than classic which is first on the list, and then wait a second, then hit escape and click multiplayer and it should load the other games.
basically, all you gotta do is find out which server is faulty... (up to which one loads untill it crashes?> pick the next one and delete it from servers.txt) and then reopen toribash... it should be fine from there
im too lazy to find which server is crappy
post back with more problems
