I have been using Adobe Digital Editions for several years. Today, when I tried to add a book to my library, I received the error message:
Unable to download
Error getting License. License Server Communication Problem:
I checked my computer authorization, which tells me that this computer is already authorized.
I have been downloading books from this particular source for several years with no problem.
What can I do to remedy this, please, without losing the books already in my library?
I am running Adobe Digital Editions 2.0.67275 on a Mac OS 10.10.4 (Yosemite).
