HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Does anyone know what the problem might be? We're playing through Hamachi, and when an opponent connects to my game, they can see me and my messages, but I can't see them. When I try to select a map/template, it says that at least 2 players are required. Please help if anyone has encountered a similar issue.
