I am able to read library books in ADE 4.5.1.133054 on my Macbook running OSX 10.11.2, and I have no problem transferring files to my Kobo. But when I try to open them on my Kobo, I get the message: "Oops! This document couldn't be opened" due to DRM issues.
My Macbook and Kobo both have the same valid adobe ID authorization. I can also download and open Toronto library books onto my iPad and read them in the Overdrive app.
I have done a factory reset on my Kobo, ensured that the Kobo is running the latest version, uninstalled and re-installed ADE on my Macbook, deauthorized and reauthorized both my Macbook and Kobo. Nothing has worked.I am stuck!
The problem is recent. Previously I never had any difficulties transferring books from my desktop ADE to my Kobo and reading them on my Kobo. Do any readers out there have any suggestions? Thanks
