FYI only: DeDRM didn't work for PDF until I removed adobe key

jazzhands11 commented 3 months ago

Question / bug report

First, thank you so much for this plugin - it's very much appreciated.

Just an FYI, not sure if this is even helpful:

I couldn't get the plugin to make a decrypted pdf until I removed the adobe key from the calibre configuration. I'm not sure why that is, and I'm glad I figured it out, but I wanted you to know that the key was causing an issue for me.

I included the log of the failed job.

Which version of Calibre are you running?

7.6

Which version of the DeDRM plugin are you running?

10.0.3

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

No response

Known bug with 10.0.3 that you need to let DeDRM automatically retrieve the key on its own. Fixed in version 10.0.9. You can close this issue.

I have the same issue, even I am using the version 10.0.9
