mac died bought new MacBook Pro...Migrated Kobo and ADE from time machine but couldn't open new book I bought. Uninstalled both Kobo and ADE and authorized again and could read new book but still can't read library books. Keep getting OOPS authorization message. Using ADE 4.5 and latest version of Kobo. Checked authorization information and laptop and ereader are identical including urn:uuid: etc.
I've dumped them both again, emptied trash, rebooted computer and reinstalled but still can't open them on ereader.
