My library uses Adobe Digital Editions to download digital books to my computer. I then download from Digital Editions to my Nook e-reader. Suddenly, I am unable to download books from my library loan page to ADE. I have used this method for years without a problem. The ADE page appears but there is nothing (no books) that are on it. 2 libraries where I have cards have tried to solve this problem. I also took it to a technician who was unable to resolve. He removed all cookies and said there were no firewalls standing in the way. What to do now?
