Thanks so far for the replies. Harper Collins did require a PID to download, which I supplied. However, the book will not open in my Kindle. I also downloaded it with the PID for my computer, and it opened just fine in Mobiread. It will not open in my Kindle before or after running it thru kindlefix. I assumed that I was doing something incorrectly using kindlefix.py. Perhaps the different format of the Kindle PID is not being recognized by Harper Collins, even though it will allow me to download. Has anyone else successfully downloaded this book, run it through kindlefix and opened it in their Kindle? If so, then I must be doing something wrong.
