Wonderful. Absolutely effing wonderful.
Well you have solved the problem with only some books opening by making it so no books open.
New books being downloaded to ADE 3.0.1 get the error: Error! Check activation
Books that were already on the library have the error:
An Error Has Been Detected
Activation Server Error
Code E_Adept_Internal
And I know what you are about to say, because when I try to return a title it says the computer is not authorized.
When I go to the Help tab the top line "authorize computer" is greyed out and if I click the second Computer Authorization line it says:
This Computer is already authorized
And then shows my Adobe account information.
Any more ideas?

Select the Adept key.
