LibreOffice - Application Crash on Export to PDF or Update Index


I’ve been using LibreOffice since 2013 to make this sort of documents and I haven’t had this much trouble before. I would like to ask for help with regards to the issue stated in the title. It’s very frustrating that this happens always.

I have a .odm file with around 50 .odt files linked to it. When I try to export to PDF or when I try to update the index (table of contents), the application hangs until it crashes. It seems to crash when I add certain .odt files to the master file.

I’m on Windows 7 64-bit. I’ve tried resetting the user profile to no avail – could it be something in my write-up?

I don’t know what else to provide; how can I help you guys to help me?

I was getting desperate so tried to print it. Still no go. It seems to hang up when it reaches a certain part in the “repagination…” process.
