I want to transfer a book from digital editions to my Kobo, but it keeps saying that ADE authorization is not compatible, so I took my kobo back to factory defaults and entered my new e-mail and downloaded ADE version 4, after setting up my Adobe ID, but when it downloaded it to the authorization of the old edition which is my partners old e-mail and apparently computer ID. We share this computer and the Kobos were purchased at the same time. Would like my ID separate and unique..
