for maps Maps : go here
C:\Documents and Settings\yourname\Application Data\My Battle for Middle-earth(tm) II Files\Maps


copy the folder of each individual map eg  Jus_sauron_best  FOLDER goes 

C:\Documents and Settings\yourname\Application Data\My Battle for Middle-earth(tm) II Files\Maps

to give  C:\Documents and Settings\Damienl\Application Data\My Battle for Middle-earth(tm) II Files\Maps\Jus_sauron_best

each folder is a separate map !! I'm sure you used worldbuilder so it is the same stuff!!
