What map are you downloading, and are there any folders in the downloaded map file that says 'exports'/'whateverfilename'?
If so, you might want to try copying and pasting everything in that folder to the specified folder in C:/>FeralHeart.
To make more sense:
Say a folder in the downloaded file says 'exports', everything in that folder I would copy and paste into C:/>FeralHeart>exports.
If another folder said 'textures' I would copy and paste everything in there to 'C:/>FeralHeart>media>textures.
