I also posted this in your first thread:

n3U,
I hate to state the obvious, but you've updated software. And if there's still a crash on the same page, there's something physically wrong on the page or in that file.
You could try printing it, or that chapter separately... but I think you need to start by making backup copy of the problem file and then saving the file, manually, as a MIF file, opening that in Frame, and saving over your other file. This should clean up any file corruption, stray characters, and malformed tags.
If the file still triggers a crash, you need to deconstruct it, piece by piece or condition by condition until you find out what content is causing the problem.

Cheers,
Art
