Quick question, ma'am. Was there a .fhm file located anywhere in the download? If so, move that particular file to Local Disk (C:) > FeralHeart > Exports then re-launch the game completely. Once ye' launch it back up and log back into the game, there should automatically be a portal in Cape of Distant Worlds.
If ye' have done this, then this is quite bizarre. There should be a portal as long as ye' have a .fhm file located in yer Exports folder.
