I had Digital Editions of this HP laptop. I have another similar HP laptop that I downloaded DE on and can read my ebooks with DE.
The first laptop will no longer recognize the ebooks so I deleted them and tried to re-download but now I get a authorization error.
DE says my computer is authorized so how do I get my books back?
Found the answer here
Follow this to the T and it will work.
Choose Start > Run.
In the Open text box, type regedit and then press Enter. The Registry Editor opens.
In the left pane of the Registry Editor, locate the following registry key:
Right-click the Adept key and choose Delete.
In the Confirm Key Delete dialog, click OK.
Your authorization will be deleted.
ADE will be deauthorized now.
Now Authorize ADE again.
do you know how to do this with a mac?
