Attacker Deploy Crash

I played an online map as the attacker. Saved the attack. Now when I want to defend against it, as soon as the comp. deploys the very first unit, the game crash. (I tried it 10 times in a row)

This also happens (but rarely) when I play as the attacker(on one of the camp. maps) and deploy a unit (this time not always the first unit, its random).

Hi there,
the next time it crashes, could you email the debug files (they get rewritten each run) to cliff AT positech.co.uk
