It seems that the answer to many questions is to uninstall and reinstall. This may be the easiest thing to do. Just start from scratch, with both the computer and email address. Use the same into. I have about 600 books and have to do that. Yuk! If that doesn't work, "Frustrated in AZ" will try to help you. He's pretty good.
OH, you might want to call the store and have them reissue the books. Sometimes they only have one download allowed. W.
Thanks for the compliment, Wanda.
The 'Licensed to a different user account' message means that when the
ebooks were downloaded, you used a user ID that's different from your
current one. IF THIS IS TRUE, you can change back to the old one by
changing the ID for your copy of ADE. CtlShiftD will deauthorize your
computer. Then, go to Library view in ADE. Click on the small arrow next
to the word 'Library'. A drop-down menu will appear. Choose 'Authorize
Computer' from it, and ADE will ask you for an Adobe ID. You can put your
old one in at this point....
If your Adobe ID hasn't changed, then you should re-install. You won't
lose your ebooks.
