Thanks! That is the only one, aside from one TPZ book, that "failed" out of 1463 books. That said, this was strictly based on K4PC testing. I do have this book in my main library from a d&t file that is fine. And yes, it is apparently no longer for sale.

I do have 6 other books that also imported as kfx-zip but will convert to other formats. I'm going to go into debug mode and check those out again and see what happens.

edit: So the other 6 books are all fine. I don't know what happened the first time, but I removed the download in K4PC then re-downloaded all of them and re-imported into Calibre and all 6 are absolutely fine and show as kfx and convert fine.
