Hello again,
I'm successfully importing several test PDF files now, but the two files that I absolutely must import for the live site will not work. I'm wondering if there is something about the files that matters. I will email them to you and refer to this forum thread.
The process stops with 'an error occured' curing the "Creation of the temporary files" bit. I can see that the folder for the images has been created, but it contains no images, and not even the temporary files that I can normally see briefly during the conversion.
In the Windows Application event log, I can see the error pasted here.
An unhandled exception occurred and the process was terminated.
Application ID: /LM/W3SVC/14/ROOT
Process ID: 6992
Exception: System.ArgumentException
Message: The directory name C:\inetpub\wwwroot\xxxxxxxxtest\Portals\6\Aricie.PageFlip\latamnewsmay1\ is invalid.

.... ok hang a second, I've just figured out what's going on and I won't need to send the PDF files through.
The failure occurs when the PDF filename ends with a zero. My files are news PDFs, currently ending in the year '2010' or just '10'. I noticed that the pathname in the error is missing the zero at the end so I tested again and it works fine without the zero.
That will need fixing, but I'm pleased that it's nothing too serious.
While I'm here... something else I noticed is that when I uploaded and converted a single page 2Mb PDF of a medium-sized poster, it was taking a very long time, so I checked the server and found it had overrun the 4Gb memory and restarted the app pool for the website and the database more than once. I checked the book images folder and there was a single 800Mb temporary file in there. That then vanished and was replaced by the two pageflip images, totalling a tiny 300kb.  Is it necessary that it create such large temporary files? Is there any kind of guideline as to what causes huge files... I note that the 18 page news file, also in colour, didn't make such large temp files.
