My first new Kindle had a bad screen defect, so they sent me a new one. When I went to sync it up with Calibre, everything worked fine, until I attempted to open one of the books on my Kindle. It then told me: "This item cannot be opened because it is licensed to a different user. Delete the item and download it from your Archived Items or purchase a copy from the Kindle Store."
Now, I tried deleting a certain book and re-downloading it from my Archive, and that does work. However, I extensively modified the metadata of every book I have from Amazon (a few hundred), and this effectively rids them of that. Is there a way to make it so that it will recognize my Calibre library as actually belonging to me?
Thanks in advance for any help.
