After doing a sync on my Kobo Touch, I was unable to download any library books. And I have seemed to made matters worse, by downloading ADE 3.0, and uninstalling ADE 2.0. Now when I tried to open a book, the options are only Adobe Acrobat DC or Internet Explorer. Any suggestions how to get ADE on there? My Kobo is 4 years old. I have been able to get books directly from KOBO, that went straight to the kobo.
