Was the initial authorization with a 'standard' Adobe ID authorization, or do EBSCO have their own separate authorization?
If it is a searpate authorization, I am afraid I can't help.
For a standard Adobe authorization it sometimes gets semi-authorized and all sorts of odd things happen. Try
- completely deauthorizing (ctrl-shift-D to ADE, cmd-shift-D on a Mac),
- restarting ADE,
- authorizing again using menu/Library/Authorize Computer
- then trying to read a book.
2) various possibilities
Did you ever authorize the Nook?
While plugged in by USB, and with ADE properly authorized to your Adobe ID menu/Library/Authorize Device.
If the Nook has been authorized that can get confused as well. Similar to above
With Nook plugged in;
- completely deauthorizing the Nook (ctrl-shift-E to ADE, cmd-shift-E on a Mac),
- restarting ADE,
- authorizing Nook again again using menu/Library/Authorize Device
- copy a book across
- and try reading it on the Nook.
There is an even more extreme version of deauthorizing the Nook when things are confused. Only do this if the above doesn't work.
- Using a file manager such as Wundows Explorer or Mac Finder
- make sure you can see hidden files and folders
- if there is a folder with a name link '.adobe-digital-editions' on the Nook, rename it
(or back it up to computer and delete it)
- start ADE and authorize the Nook.
There are bugs in ADE2.0 that mean it won't work with some devices. Try 1.7.2 instead.
Yhat might help with both 1 and 2.
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
