I could use some help on this too. I downloaded the Mobipocket reader, a free sample, the mobidedrm python stuff is installed and I get as far as opening a command prompt window then to the free Mobi sample I have but the Visual Kindle Guide doesn't help me accomplish the task at hand. I'm helpless when it comes to computer-speak!
I don't want to violate rules so if someone could PM me step-by-step instructions I would be deeply grateful!
