I don't know whether this is a solution or not, but you can check the
digital rights assigned by the publisher for each book and see whether
there's a problem.
When the ebook is displayed in the Library view of ADE, place your cursor on
the avatar/title/cover of the ebook. A small carat will appear. Click on
the carat, and a drop-down box will show you some choices. Pick and click
on 'Item Info'. You'll see the digital rights displayed in the lower half..
Also, all of your activity in playing with the software hasn't erased your
ebooks, but it HAS changed your account information. That can cause you to
get the message about 'another user' because something is different about
your ID and password.
This isn't a list of instructions on how to fix your problem, but I hope
Thank you for your support, I finally got the problem corrected. For those having the same problem I was, here is what you need to do:
