Reply To: Locking up when making a pdf from a book

I wrote a quick how to on troubleshooting files to discover their issues

In your case you have “divided and conquered” and found out that you can export half the book and then the other half and it works.

I suggest continuing this practice by exporting 2/3 of the book and see if it crashes – and if it does then try narrow down by exporting back 1 chapter at a time to where the problem chapter may be.

Let me know how you get on.

===============

By the way – it might be a better workflow to export all your book files to IDML from your older version of InDesign

– then open those IDML files in the later version of InDesign

– then generate a new Book File and add the new files to this

This script will allow you to make IDML files from a Folder of InDesign files make sure you’re in the older version of InDesign (play with it and you’ll what I mean)

Speed things up for you.

If you’ve already made a load of changes to your book and this is too much work to go back

I suggest you export all your Files from your latest version of InDesign with all your changes to IDML.

Open them in the latest version of InDesign – resave them as InDesign Files.

Then Create a New Book in InDesign and try the export.

Honestly it won’t take long.
