Cannot remove DMR

[Emiliecd123]

Question / bug report

Trying to remove DMR on a book i bought on Rakuten. I need to convert it to epub or PDF to view on my ipad. I followed all this but still not working and Calibre keep telling me it's protect:

Make sure the DeDRM plugin is installed in Calibre

Customize the plugin (Preferences -> Plugins > File Types > DeDRM) and click on the button called Adobe Digital Edition

Make sure your ADE key is there in the list. If not, click on the green + button to automatically add it from your ADE installation

Save changes and restart Calibre

Import the protected ePub into Calibre. During the import process, the protection will be removed

Now you can export the unprotected ePub from Calibre to your computer. The resulting ePub file can now be opened in Books or any (e)Reader

Which version of Calibre are you running?

7.9.0

Which version of the DeDRM plugin are you running?

v10.0.3

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

No response

Delete your Adobe key from DeDRM customization. Add the book letting DeDRM automatically retrieve the key on its own.

Where did you see those instructions?

Thank you so much ! The key was the problem. I found those instructions a multiple time on Reddit. Not my field of practice as you can see, just a nurse here lol

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