This may have been discussed before, but when I rename Civ4 map files as Warlords maps and try to add the new civs through WordPad, the maps fail to load when I start the game. I'm using Rhye's Earth24 mod, can the new civs be added to the map? Thanks.

To add a civ on a map, you have to add :

a new team
a new player

If you add a player in a team not defined, it could cause some problems...
