Hi, I am new to multiplayer, please help. I have been able to connect to multiplayer with my brother using the 'connect by IP address' option prior to the middle of last week, when I updated to 2.5.4.28090. My brother is running 2.5.4.27430. Connections were fine until I updated. I am using a BGW 210-700 modem/router and my brother is using a Netgear 3400V3. Now when connection is attempted, with him running as host, I get a 'server offline' message when I attempt to connect. I am unsure as to what to do next, although I suspect it involves maybe port forwarding. I am a bit hesitant to do this as it may mess things up and I am not very technically competent. Would it be possible/helpful to roll back my update?
