When I borrow books from the library I get this message when I try to open the book or transfer it to my Kobo. It doesn't happen with every book, just 85%.
I have erased authorizations and reauthorized. That didn't work.
I have dragged the activation.dat file to the trash. That didn't work.
I have uninstalled and reinstalled ADE and that didn't work.
