The player who got this error message most likely got it because he was trying to open the game in the stock Version. While most of FQM's changes are in the new quadrant types, it also has some changed and new planet type information and different population modifiers, so the players do need to use the mod in order to play.

The replacement player's empire name and shipset are the same as the original because replacement players don't get the option of changing them. The game has already started, so all details about the empire are already fixed. The replacement player just gets to take over the empire the original player set up.

Edit: That replacement player needs to change his empire's password. Zarathustra also needs to do it. Their empires currently don't have passwords, so anyone can load the game as them and see exactly where they are and what they're doing.
