HELP! Calibre problems with Sony PRS 600
I've just installed Calibre to use with Sony PRS 600. Following instructions I loaded my books into a Calibre library, then transfered books to eReader. PRS 600 identifies 489 pages, but 18 pages into the book and beyond are blank. This occurred with each book I've tried to download.
I can read the book on my MacBook with OS X. eBook format is PDF.
