Are you trying to get the map you've downloaded to show in cape?
Before you do anything, delete what you have previously done and start new. Then find the downloaded file and read the 'README' if there is one. If there is no README then place the downloaded file into LocalDiskC:\>>FeralHeart>>Exports and if it comes up with an option to replace things then replace them. After that restart FH and see if it shows up if not locate the Dowloaded file (Which you put in exports) and move everything in that folder into Exports too.
Make sure you read the instructions given in the README carefully (If there is a readme).
