Question / bug report

I bought the graphical novel Monstress - volume 3 from Amazon Kindle, downloaded it to my pc and tried to remove the DRM by importing the book with 'Add a book' in Calibre. However, I am experiencing an issue that the voucher cannot be decrypted. Does anyone know why this error happens and how to fix it? Thanks in advance! And thanks to the contributors for maintaining this software!

Which version of Calibre are you running?

7.18

Which version of the DeDRM plugin are you running?

v10.0.9

If applicable, which version of the Kindle software are you running?

2.5.0 (70951)

Go back to Kindle for PC 2.4.0 (70904) aka 2.4.70904. DeDRM stops working with newer versions. See info about blocking updates under method 2 here: https://www.mobileread.com/forums/showthread.php?t=361503

@ElleKayEm Thank you very much for both a correct and quick answer!

For anyone else seeing similar issues, here is a link to the official 2.4.0 client: https://kindleforpc.s3.amazonaws.com/70904/KindleForPC-installer-2.4.70904.exe

After this, I had the issue that for my specific book the KFX format caused some conversions issues. Specifically this error:

Following the steps here from the OP: https://www.reddit.com/r/Calibre/comments/1e9qmu2/comment/lehsxb3/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

This will lead you to not use Calibre conversion but rather the 'From KFX Input' tool to convert to other formats which does work. This allowed me to convert the book to .cvz with DRM removed so I can finally use other readers than the Kindle reader.

Thanks for the additional info.
