If my memory perceives me, when you first open the download application of Red's, it'll ask you a particular destination to download it in. Whatever destination you choose, usually located somewhere in your computer files or the main Feralheart directory, the download will extract a folder to that given location before automatically closing. There is generally no given problem, as it has indeed downloaded what you're seeking. All you have to do is find a folder that has been placed in the destination you've chosen and merely open it. Within the folder should be what you're looking for, Red's maps in this case. Hoped my rough explanation solved some of your confusion but if ye' need something made a bit more clear to ye', feel free to inform me.
Have you extracted the given contents within the folder and placed them in their correct destinations? If so, then it may either be the server acting up or something's been misplaced. My apologies for the unfortunates you're facing, Ms.
