epub DRM removal for Overdrive books does not work #20

I have installed the latest version of Calibre (2.31) and also installed the latest version of plugin (6.2.1) and yet it doesn't remove the DRM. The log says that it thinks its a DRM Free file. It is not.

Any idea what's going on here? The file is .epub and it comes from Overdrive, according to the XML internals, its using AES128 and Adobe Adept. I am including the XML file for it. Anything else I can provide to help figure out why its not working?

(contains the actual epub file as well as a folder containing the deconstructed internals)

Add support for "hardened" Adobe DRM

What took the most time was not reverse-engineering
the scheme, but actually finding books using it...
