For once, I thouht maybe I could provide a little help. I was getting this error message today (Kindle for PC doesn't show any of my books - I have to remove DRM first. I put the books on my kindle, want to read it on my
PC, and I have to remove DRM!). First, I tried different PIDs. When I had tried everything, I tried quotation marks. Nothing. It was a 5-word title, so I changed the first instance to one word. Nothing. Then I changed the 2d instance to one word - done.
