Can't download custom soundset


I have just purchased the supersyn sub and started to create my own soundset. While creating it I uploaded multiple times as I made edits. The name of the set is Dread Metal Sky

Now I have gone to a 2nd computer and opened soundset creator. I see 3 custom sets: Dread Metal Sky, Dread Metal Sky (1) and Dread Metal Sky (2). If I try to download the first it never completes (going on an hour with great internet) for the other 2, I get an error (I can’t find an error code). I then opened the Sci-Fi Syrenscape Windows app, and see the same 3 soundsets. When I try to install any of them, they get to 100% download and just seem to hang there.

Any idea how to fix this? Thanks!
