Problem removing DRV even with the plugin installed

[tinhomaranholi]

Question / bug report

So, I followed the step-by-step tutorial on giuthub in my Calibre, but the problem persisted. Here is the log below.

Ps: I downloaded the e-book through my Kindle and imported it into Calibre.

Which version of Calibre are you running?

7.21.0

Which version of the DeDRM plugin are you running?

10.0.9

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

Kindle 5.16.21 (4289750037)

You will not be able to decrypt a book downloaded directly to your Kindle. Is it an E-ink Kindle and not one of the brand new 2024 releases? Then go to your Content Library on the website and use the "Download & transfer via USB" option choosing that Kindle. You will also need to have that Kindle's serial number entered into DeDRM's customization.
