dx error

Hi Folks,

Got quite a few turns in before my first crash, but I finally got one with the same "DX error: invalid call" message that I regularly got with the beta.

I've included the link to the file, but I don't know if it's related to the crash, as it's time-dated three hours before the crash.  However, that's about the time I installed the game, so I don't know what it could be.

The crash occurred when I attempted to give a new destination to my stack.  The stack was not in a city, nor was the intended destination.  Hope this is helpful.
