For this problem, you need to deauthorize and authorize ADE again.
Please follow below steps:
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.
Error will be fixed
i did the instruction several times. nothing happend.
When i start the ADE there is only an empty ADE Desktop. No books.
Might be there a problem with the path of library, where the Software the books can find?
Because when i try to import a book which i tried before (and i cannot see it still)
there pop up a notice with the info:
"Document .........epub cannot be added to the library.
The book, you want to add, is already in the library."
Unfortunatly, i cannot see the book in ADE.
What went wrong?
Thank you for help
