It keeps telling me that the document (which is library book I borrowed from overdrive) is not currently authorized for use with my Adobe ID. I have deauthorized my Kobo device then download the eBook to my ereader again but it still tells me it's not authorized. This method of deauthorizing and then re-loading the ebook into the ereader worked for the first book but for the following books the same problem happens again. Should I follow this method Activation errors for this problem? Thanks!
