EBO : when I join the lobby, I can't see the other players

This happens sometimes. Sometimes a restart of the pc is all that's necessary. Sometimes you have to mess with network adapter priorities. If you go to Network and Sharing Center in Windows Vista and beyond (found under Control Panel >> Network and Internet), and go to Change adapter settings, press the Alt key to bring up the menu bar, go to Advanced >> Advanced Settings, you will want to be sure your Hamachi adapter the lowest on the list (highlight and press the down arrow to move it down). You can make it go as far down as one level above [Remote Access connections]. The netcode for the Rome engine isn't superb...

EDIT: Also make sure you have a green (direct tunnel) connection with whoever else you're trying to play with. Relayed tunnels over Hamachi/Tunngle/Evolve/Wippien won't work.
