de-DRMing Kindle books

[beatrice_otter]

I read ebooks on my computer.  I use Calibre and have the plugins from A guide for the perplexed.  It says that if you get Kindle for PC, you don't have to customize any of the plugins; the books should be unlocked automatically when you add them to Calibre.  Except it's not working--the books is not unlocking.  Why not, and how can I fix it?  I moved the books from "My Kindle Content" folder to the folder with the rest of my ebooks in it; does that matter?  I've tried adding the book with nothing changed in the plugins (although it does already have the PID from other stores).  I've tried adding the book with my Amazon password entered where the PID goes; I've tried adding the book with the e-mail associated with my Amazon account there; I've tried adding it with "____'s Kindle for PC" there.  (Those are the only three identifying things I can think of or find.)  None of them have worked.  Help!

Unswindle python scripty thing, at I♥Cabbages, your one-stop blog for ebook drm things, written in language that's probably easy to follow if you speak any code at all, which I don't. (The magic word for ADE is "inept," if you wind up needing to search for that.)

Or you can give up on removing the DRM yourself and google for [book title] [torrent].

SO NICE OF AMAZON TO MAKE IT CONVENIENT TO READ EBOOKS, ISN'T IT.
