Problems with decrypting .azw (kindle for pc) - I think I'm missing something ! (Solved)

Question / bug report

I'm trying to run DeDRM on Kindle .azw files. (I was successful until about 2 years ago when things changed). I've installed latest versions of Calibre, DeDrm and Kindle for PC 1.33. I'm left with the .B00..._EBOK.azw file in Calibre which will not read.

The attached log file (nodrm_dedrm.txt) gives details and refers to ' a default Kindle Key' I've listed contents of ../B004UJAN68 at start of log file nodrm_dedrm.txt

I'm not sure what else I should be doing.

Which version of Calibre are you running?

5.42

Which version of the DeDRM plugin are you running?

10.0.2

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

No response
