My friend and I are trying to run a LAN game. We're using hamachi, no matter which one of us tries to start the game the other gets the message that the server has timed out. Whoever has started the game can get in but neither of us can join the game. He's on a 10.5.8 OS Mac, I'm on Windows 8.1. We'd been able to do this about a year ago but suddenly we can't.
