Game crashes when I die firing tau cannon

It’s happened several times already, I didn’t see a post on it on the first 2 pages, so here it is. All in the title. Doesn’t seem to crash if I simply have the cannon out, only when I’m firing.

Specs:

3 Ghz Core 2 duo
4 Gb RAM
1 Gb EVGA GeForce GTX 460, Driver version 9.18.13.697
Windows 7 Ultimate

Not sure which of these MDMP files is the correct one, so here’s both haha.

Having a blast, great job guys! No wonder Half-Life is the most influential FPS ever! Back to gaming!
