The problem:

Twighlight of the Arnor crashes when after I have selected my race's spaceship design, just before it loads a map. 

What I've tried:

Uninstalling all gal-civ products and redownloading from impulse.  Also I made sure that each of the other products (galciv2 and dark avatar) launched to the space map successfully after race selection.  It is just Twighlight that crashes as of version 2 via impulse.  Previously twighlight ran fine.  Drivers are up to date.

System:

Windows Vista 32bit sp1, Quadro 3500, on board sound, 4 gb ram.
