Access Violation

[Brivtech]

I've been violated!

I'm getting this:

Access violation exception at offset 0x00068ABF


What does it mean? Why is it happening, and most importantly, how do I prevent it?

I'm getting it with a file that I've been exporting to PDF. It has been working fine, until now, and when I try and export, or do something like convert to curves, it keeps coming up.
