help with ADE

[Moderator moved from Help with using Adobe Muse CC to Adobe Digital Editions.]

I installed ADE on a new laptop. I have it on an old laptop, but when I did it on this laptop, my books did not transfer, All that is on thee is the Get started book.

I have many books on the old one.

I had installed it on another computer, but then uninstalled it, and installed it on this one.
