Lost bookshelves in Digital Editions

[wldwheeler]

I'm a researcher and I love Digital Editions. My Digital Editions had 790 books and journal articles. I had about 30 bookshelves, organizing my material. Two years ago, my computer crashed and just now have it back. I thought I lost everything. Digital Editions works, all my 790 material shows up but I now have only six bookshelves with only one book each in them and it seems I lost all my notes, highlights, and bookmarks on my research material!  That is bad.

Is there any way of recovering my lost bookshelves and highlights?

What do I do to preserve my notes, bookmarks, highlights, bookshelves?

This is a pain in the ass, if I have to reshelve 790 books and journals!  What happens if my computer crashes again?

In future upgrades, can you fix this with a "reboot Digital Editions folder.exe", that saves our catalogued material?

I first used Digital Editions on an HP Quad4 Vista Ultimate laptop. Since there were a cascading amount of freezes, hacks, shutdowns, I was forced to go to higher, newer software. I went to Windows 10 which I didn't know at the time, my laptop wasn't configured for. So I went to Windows 10 but then I couldn't do anything because it was so foreign. It was mind-boggling mess. So then I went to a Vista skin over the Windows 10. Ran, like usual, my cleaner software, and laptop crashes. So now, due to poverty, I finally get it fixed and it has Windows 8.1.  Now, I go to my Digital Editions to resume my writing career---and all my previous work has disappeared down the rabbit hole. So due to Microsoft's deficiencies, I have been forced to upgrade constantly and Windows 8.1 is not going to last forever.

I see that there are no responses yet. I would like to know that if I start up again using Digital Editions, I can preserve my research. If I can not, then, I can't use your product. Why would anyone. How do I preserve my work, my highlights, my bookshelves, my bookmarks, my notes. I lost a lot of material, a lot!  I also lost productivity, and now more time to repair what I lost. How do I preserve, transport my work from one platform to another or save my work? Or like at Microsoft, they tell me to use somebody else's software.
