I've been using this plugin for a few months, and suddenly it failed.

Today I added the custom column "read" and started going through my library. At one point I encountered a book that still had DRM on it. (An Epub, in fact.) Afterward the plugin stopped working.

I restarted Calibre but the plugin still doesn't work. I'm not sure what I did wrong. (Calibre maintains previous counts, but will not add new ones.)

Also, does anyone know how to change column names? For some reason it says "words" when it means "pages".
