I'm trying to extract a couple of the free Kindle books I downloaded to my iPod, just to see if I can. I jailbroke and copied them over, and tried to run mobiddrm using the key I generated from my UDID and got the following:

python2.5 mobiddrm01.py B000FCK3C8_EBOK.prc maxride.prc "KT18ZMY*6X"
MobiDeDrm v0.01. Copyright (c) 2008 The Dark Reverser
Error: no key found. maybe the PID is incorrect

I did the checksum thing and it said the key was correct. As far as I can tell, it is encrypted (at least, when I open it with FBReader, I get gibberish).

Any suggestions? Did I perhaps generate the key from the UDID wrong?
