DeDRM not working with AZW3 and Calibre 3.30

[krjackson]

I'm trying to convert an AZW3 book I downloaded from my Amazon account. I've entered the serial of my Kindle Voyage into the plugin. Yet I get an error:

Convert book 1 of 1 (Ars Vercanus: Advanced Magickal Techniques)

It looks to me like the DeDRM plugin is never being invoked?

DRM removal happens when you first add the book, not during conversion. Here's how to get the log:

@ElleKayEm You should totally slap me on the wrist with an RTFM! for not digging into the FAQ. Been a while since I used the plugin. Doh!
