My friend recently went online in Monster Hunter Tri, solo, just to look at the missions and maybe do one. Before he made it to the Mission desk, another player popped into his city. Immediately afterwards, he lost his connection. When he tried to reconnect, he got a message saying he was banned for 10 days. He didn't do anything. The only thing is he's playing from a backup, and that's it. Is it possible that some jerk is running around with modified files that makes other users look suspect? Anyway, is there a workaround of fix, or will he just have to wait it out?
