I guess it's something to do with the sound. In fact, the screen freezes and the sound loops for a long time before CTD. Any idea?

Based on earlier reports similar to yours I believe the issue is a random generated group (RGG) set in the harbor traffic file inside truk lagoon has a typo causing it to regenerate at too high of rate...figure if accidentally set to 100 percent chance 24 hours (sometimes things default or are left but is anchored, when player comes within range can encounter hundreds or event thousands of ships, game can't handle making that many render in 3D, so it causes a freeze and CTD. A lot depends on date/year.

I have been out of town so unable to take a look and correct this as of yet. Once home, I will look into this.
