My wife's Aura needed to update for some reason (she was perfectly happy with it the way it was). After the update all books are gone. (I only use Calibre to put books on, not Wifi). After a while she could not even find stuff anymore, so I used the links to go to an older firmware (3.8). This worked fine, only for some reason she can't remove books from the device anymore. So I tried to update to the latest version which again worked OK, but after some time it wanted to connect to Kobo desktop, which I don't want, since then it will sync and I don't want that. So I put back an older version (3.19). Again this wants me to download Kobo desktop but this does not work (the download works but the device does not connect. Any ideas what I should do?
Several things come to mind like reinstalling desktop from scratch, because right now I can't even install any other software (the device does not show up in Windows 10)
