InDesign Will Not Print to PDF

Question

Good morning;
I am currently running InDesign CS5.5 on Windows 7.
I have a 103 page document which will only print to page 41 when I choose "Print to PDF".
It does not export any pages, when I choose "Export" and select pdf, or when I choose a "PDF Preset".
All 103 pages print to paper fine.
The document was working fine earlier this week. I could print everything to pdf.LiveFlight reports no errors
I opened an earlier version of the file, and it also could not print to pdf past page 41.Once again, there were no errors
I've tried restarting the computer, shutting down, etc
I was able to successfuly print the following to pdf:
a 45 page blank document
A 49 page document with images on each page.
I deleted page 42, and it was able to go two pages past. This is the log generated after the operation is complete (and unsuccessful):

Are you sure it’s been fully generated? PDF export is a background process.
To be sure, select view PDF after exporting in the export dialog box.
