captainllamas Posted August 12, 2013 Posted August 12, 2013 My brother and I are trying to play a LAN world that he created. He created the server and I'm able to see it in multiplayer, however when I connect either via DirectConnect or Join Lan, I either get a "name already used : disconnecting" or a crash with the following log .... any ideas?? thanks, CaptainLlamas ---- Minecraft Crash Report ---- // You should try our sister game, Minceraft!

dwwojcik Posted August 12, 2013 Posted August 12, 2013 1. Don't sign you posts. 2. Are you attempting to log in in offline mode?
captainllamas Posted August 12, 2013 Author Posted August 12, 2013 2) we weren't trying to log in in offline mode. We were afraid we would both have to share inventories if we did that.
Gildan27 Posted August 12, 2013 Posted August 12, 2013 Are you both logging in with the same user account? You both need to have your own registered Minecraft username to play multiplayer.
