If you have a PNG Image file,Map file,Mesh file, and a bunch of CFG files then your map isn't exported yet.
Go on the game, click the "Tools" tab underneath login, then "Mapmaker". Type the name of your map in the box then click "Export".
Sorry to rain on your parade, my boy, but it seems that shes speaking of a downloaded map, not a map she created -3-
Well, either or not it's download the map still needs to be exported to work. This is from the readme file in the exports folder:
Place your friends' maps here!
"Maps must be exported from the Map Maker.
Files types included are:
.fhm
.fho
.fhs
.fhw"
So either way you can't put a PNG Image file,Map file,Mesh file, and a bunch of CFG files in the exports folder and expect it to work; .fhm, .fho, .fhs, .fhw files only. x'D
And fire, it's public because some people have downloaded your map somewhere. ^^
