I've got a file in InDesign CC 2014 and every time I try to export a PDF InDesign hard crashes. The file itself is about 60 pages but there are nine others in the series of documents just like it that don't have any problems. I tried creating an IDML of the file and exporting that and I get the same thing. The file itself seems intact in every other way.
I'd be grateful for any tips on how to diagnose and fix this issue!
The typical way of diagnosing such a problem is “divide and conquer!”
If you know what page the export crashes at, try isolating the problem to a particular page. Once you know the problematic page, make a temporary copy of the document and see if by removing graphical objects, one at a time, the export succeeds. Once you isolate it down to a placed graphical object, you need to see whether editing and or resaving that object, possibly in another format or with different parameters resolves the issue.
Good luck. This is not usually easy.
