Grell, you ought to start a new thread for your problem, seeing as people will now think you've answered Cynder's and neither would get answered.
Cynder: You may need to put the map file under "FeralHeart>media>terrains". Make a copy of the .fhm file and do that, leaving one copy of the map where it is, under Exports. That sometimes works.
If this fails, ask whoever made your map if you need to put the files anywhere else (e.g. any .fho files under "FeralHeart>media>objects", etc.).
If others are having the same problem, ask your map maker to re-export their map.
Grell: First, you'll need to export your map. Under map maker, there should be the option to do so. After you've pressed the "Export" button, you should have the .fhm file underneath "FeralHeart>exports" (not under FeralHeart>media>terrain, that is the MAP file).
