Alright, I'll take a look and test it.
Oh, after downloading I already noticed what the problem is without trying to go there. You uploaded the .map files and the .cfg files. So I guess you didn't export your maps, right? If not, open them in Map Maker and simply click 'export'. After that you should find .fhm (the Map itself) .fho (the Objects you put in your map) .fhs (the Sky, if you made one) and .fhw (the weather, if you added some) files in your exports folder. Those are the files you have to put up for download. Then your friends have to put them in their 'exports' folder.
