Re: Start Campaign problem
The map_faction_name files are the faction maps that are dislpayed when you choose your faction.
The vc_map and vcs_map files are for the map in game for the victory conditions for the long game (vc) and the short game (vcs)
They are not required for game play, just eye candy
radar_map(s) are eye candy and not required for the running of the game
disasters.tga is a dinosaur from RTW and has no function in medieval2 or kingdoms
The imperial_campaign folder only requires the text files for the mod to work
Summary: your fault lies somewhere else. Did you check your log?
