Yes, they have a new Windows app that you have to use. First uninstall the old Kindle program and then install the new Windows Store app.
Hopefully the wizards at Epuber can overcome this new hurdle.
Fortunately Epubor still works on Barnes & Noble Nook app (and probably Kobo?).
So until the wizards succeed, I'll need to by my ebooks at B&N. :-( I hate their app and their website.
