I create a monthly magazine - usually 72-88 pages - which is created in ID as about 10 documents, combined into a book.
All works OK until I come to export the file to print. Every time I Export Book to PDF, no matter what the settings (smallest file size, High-quality Print, Pass4Press etc) it always 'hangs' at some point of the process, requiring me to force quit ID. I then have to export each document separately and then combine into one PDF in Acrobat Pro.

Another possibility is corruption in your InDesign preferences. Try restoring your preferences. Here's how:
