I use a MAC, and had a Sony E-reader. Recently, the Sony reader died and I decided to go with the Nook instead.
I have more than 100 books in EPUB format, and tried to add them to the Dgital Editions Library. I first was able to do so a couple at a time with no problems.
THen I decided to go "whole hog" and selected over 90 to be transferred into ADE. Now, all that happens is I get a message saying "Verifying Document" but no progress is made and ADE is frozen completely.
I tried uninstalling ADE by following the uninstalation procedure as described on the Adobe website, and downloaded the stand alone version of ADE.
When it started up, I got the same message and the same "frozen" state.
