OK so i am running a server on my machine and my friend and I were playing just fine last night but then today he wasn't able to connect. After a little forum searching we found out that it is because one of our versions was updated by mistake and our clients were running different versions. We have also determined that it is his system(client) that has the updated version not my system(server). The problem we have now is no matter how many times he has uninstalled, opted out of beta, manually deleted files and reinstalled it still downloads the 958 version not the 956 version.Thanks in advance for the help! =-)
