Plum Tree App is shutting down?

I have too many family trees (26) which are all interrelated and I'm having issues with downloading more then one. and I can't make new family trees else where because the majority of the sims from Gen 1-5 are deceased, ex-sims, have been bereft of life of life and it also means they got culled a long time ago depending on which generation they're. I don't think there's an option to import family trees from other places into Family Eco or anything. And I just about to write Swanson Chapter 7.14 for the first time in over 2+ years.

I can't even download any of my 26 family trees from the site. I was able to download 2 but now I can't anymore every time I try it says "something gone wrong with my download"
