I have ultimate edition. I have since figured out how to use this device. Just drive it INTO a star and it destroys everything around that star. Thus if you are trying to destroy an enemy starbase that is OUTSIDE the star system it will not work. I did however have the joy of running it into the Krynn homesystem and taking out in one fell swoop the Krynn homeworld, two additional Krynn production planets. Oh the joy!
Thanks for lettting me post.
