Not converting to non-DRM
I've been using Calibre for over a year, installed the DeDRM plugin and it works fine on my main PC. I'm still using 2.0, as it works perfectly well for all that I want it to do, so I haven't found it necessary to update.
I got a laptop PC and installed the latest Calibre (2.20) and then d/l and installed the DeDRM plugin. It shows up in user installed plugins.
But when I try to convert a book (any book, I've tried a few), I get a popup that tells me I cannot convert. I was able to convert the same books on my main PC without any problem.
What is preventing the conversion?
(Both machines are running Win7 Ultimate, 4gb RAM, and dual core 64 bit.)
