If that is from or for an E-ink Kindle (not a Fire), then you need to correctly enter that Kindle's serial number into DeDRM's customization.

[slucyk]

Yeah I added the serial number. Im wondering if it's because the kindle is so old and barely functional (I think it's over 10 yrs old). I tried it with another kindle linked to my account and had the same issue where it was unable to remove the DRM

[ElleKayEm]

An old Kindle is not an issue as long as it is E-ink and not a Fire. If you are you downloading from the website, make sure you have chosen the correct device. And make sure the serial number is entered correctly by copy and pasting it from the website. After you have entered the serial number, restart calibre before re-adding the book.

I tried it again on my newer Kindle and reinstalled Calibre and the DeDRM plugin and IT WORKED! Thanks so much. Appreciate the help!

If you're all set, then you can close the issue.
