Like others in this thread, I was having problems stripping my ePub files and was having the problem because I didn't grab the key until after updating to 1.7.2. Determined to not have this get the best of me, I setup a new virtual machine in VMWare Workstation, installed all the python, pc-crypto, and grabbed the scripts. I then used the setup file for ADE 1.7.1 provided earlier in this thread and authorized it. Ran the ineptkey script, and used the resulting key file to decrypt an ePub which would not with the 1.7.2 key.
All is now good in the clean ePub universe.
