I see.. I've actually been trying to connect to your server and I don't think I have any saves on it. XD And what would an invalid username be exactly? I just have it set as Dave, nothing else. .-. Some people no username can also help, but I'm not entirely sure how true the claim is and come next update it won't be possible anymore. Try a couple of other servers, as much as it pains me to lose a player, you might as well get a shot at multiplayer. If that still doesn't work... kind of stuck for me because I don't know anything else that might help the issue. Sorry. Nah you're fine Connall, out of curiosity, what's the port? It might be that the one I use is wrong.
