Borrowing Library books to transfer to Nook Glowlite. While trying to open with A.D.E. 4.0, I get a "check activation" message. What to do??
I am also having this problem, only I hope to transfer the epub to a Nook Color.
-- EDIT --
I Pressed ctrl + shift + d to force erase my computer's authorization. Then I reauthorized it and was able to load the ebook into ADE.
