If you buy a Mobi book from someplace other than Amazon, you have to provide a PID of some sort so that the vendor can encrypt the file with the PID.
If you can download that book (not via your Kindle 3) and know the PID you provided, you should still be able to process it, I would think.
My previous post was only about books bought from Amazon via your standalone Kindle device (in this case a Kindle 3).
Hope this is clearer,
