Just read my post above =\Im not too sure whether its running on the port 29071.
It has a screenshot, which explains an issue perfectly.
Stop running game client (MBII itself) BEFORE running a server.How do I change this?
Start the server, THEN launch game (if you even need to run MBII, actually).
OR, change port in game's config, NOT server's config:
My Documents\My Games\OpenJK\MBII\openjk.cfg
Game is not a server, but game opens port anyway.
By default, that port is 29070.
Port that is already opened cannot be used by any other process, including MBII server.
Either shut down a process which took over 29070 (Movie Battles client), or make Movie Battles use some other port.
