"Cannot find __Terrain.png"

[FoxlessCrow]

Fff..  Making a map using gimp, I made one before and it was a success.  Now, whenever I put the .png file into terrains and I try to open it in feral heart, it says "Cannot Find __Terrain.png!"  I've remade it, and renamed, and put it in defaults and terrains, as I was recommended to do.  I've spent at least an hour browsing the help forum, and can't get any answers.  So, I know there are topics similar but I seem to not be getting any help.
Any help appreciated, thanks.

Have you tried saving the map and then placing the png into the map folder in terrains?

I tried doing that but there is no map folder, even after I've saved it.

If your game isn't creating a map folder for a map you save in map maker, I'd try reinstalling. It should be making  a folder with your map name.

Alright, thank you.
