I think my company just updated our licences and suddenly ID crashes when trying to export to pdf. I tried saving as a new file and exporting, it worked a couple of times, but at no point would it export over an existing (closed) pdf.

Added to the above, my keyboard suddenly decided not to respond. I put in new batteries, but it did not work until I did a restart.

I have tested exporting from indd, idml, both did not work. I'm re exporting as I fix errors I see in the pdf that were missed in ID.

I tried another restart.

No attributes have been changed.

And still it crashes, EVERY TIME
