Ok, I went back and looked at the beginning of this post.
Are you saying that I have one PID *from Amazon* and another when I import my AZW file into Calibre?
In either case, is it possible to view the PID using Calibre (or some other tool) to verify that I'm using the correct one? I got mine from the website which generates it (
