Whoops! I think that element was not included in the instructions I posted in the Maps forum, which WeaselOp quoted in the beginning of this thread.Did you add the scenario search folder path?
Point 5) of the instructions should read, then:
Select "Rules" and "Players/Scenario Data"from the options presented to you next (you don't want Map info or Player Data info imported to your map, unless the mod/scenario has custom player information -- I don't think LotM does).
