    Error: check activation message


      Adobe Digital Editions is authorized on my computer running Windows 10.  When I try to download a book that I have checked out on Overdrive from my library, I get the following message:  Error: check activation

            Hi, can you please explain what these steps are intended to do?


            I have two Adobe ID's - one for my business, and one personal for ebooks.


            Will this have affect both of them?

              The error say that activation are not right in your system. You must remove it and authoirze again. Which of Adobe ID do you used its your decision.
