Lightroom 4.4 book module won't print to pdf, blurb or jpeg

I'm using Lightroom 4.4 and for some reason I can't get Lightroom to export my book to PDF or Blurb tonight. The images haven't moved on my hard drive (drobo). I already sent the book to print 2 weeks ago & have the hard copy. The images all show at the bottom of the book module & the pages display correctly. LR 4.4 has the latest updates. What am I missing?

Windows 7 Professional.

I know my post will not offer any help for you cuz you must have sovled your problem already. But to help later viewers, I still decide to post the answer here.
First, I think you can receive a better response by posting this at LR forums.
Then, back to the question itself. do you have this problem when you are trying to export one or two-page pdf? Cus I found a post talking about similar issue. Maybe it can help you.
