Blender 2.66 Fire Domain problem?...

Hi all!..

I seem to be having a problem with creating fire in blender 2.66
After setting up the scene, i.e fire, i go to the physics tab, set the fire to the amitter to outflow!..
Then going to the box that’s going to be the domain, i go to the physics tab once again and set it as domain but as soon as i do this, blender closes down?..

I’ve used fire before and everything else within blender is working wonderfully just can’t seem to figure out why this is happening?..
Would be most greatful for the help!..

Just to add, loving all the new tools and updates, great work!..
