Hi Stream Recorder

And thanks for the quick reply. I am using the 4.0 archive, and have already put my PID, comma (no space), and serial number into the plugin. Calibre will not import without an error (the book *does* import, but will not open, and will not convert.)

I began all this with a standalone, command-line mobidedrm.py file, which claims a bad PID, and worked my way up to the 4.0 archive, making sure that all software dependencies were met and any customization (such as PID and serial) were filled out. Also upgraded to Calibre 8.6 so I could try the "find upgrades" feature for the plugins... no good. All kinds of other stuff, but no plugins of the nature needed for import/conversion.

I'm at a loss as to why this measly little prc file should be so difficult and intractable. Wish I knew more about coding so I could just rip it out by reverse-engineering/brute force!
