Americas Campaign: completed but no unlocked factions

[prophetUK]

I completed a Long Campaign in the Americas expansion, as the Mayans (30 regions + Chichen Itza). However, it doesn't seem to have unlocked the other factions to play (e.g. Tarascans). Any ideas why this is the case?
I had no problems in vanilla MTW2 unlocking factions after completing a long campaign as France...

Not too sure, but you can always move the factions in descr_strat from unplayable\unlockable to playable.

Go to ->
SEGA\Medieval II Total War\mods\americas\data\world\maps\campaign\imperial_campaign ->

Double click the "descr_strat" file and put all the factions under "playable".
