all of a sudden keeps crashing upon host !?

[onomastikon]

This is the first time I have ever had any crash with the game whatsoever.
I have been playing SP, and in round 79. There is only one opponent left, and as I go to storm his castle, the game crashes when I hit host. It does not hang or otherwise screw up the computer.
Playing on Win2000, PIII 1000 MhZ with 512 RAM.
I cant think of why it should crash -- anyone know what I can do?
thank you

EDIT: I just checked by taking the game folder and putting it onto my laptop and checking there. It is a win98 pIII, and it crashed there too. The game just ends, but otherwise no system problems occurred.
