I think the license expired in 2003 or so. It was the "silver package" and not the "gold" one if I remember right, but its been too long. It cost less, but you only had access to upgrades for one year or something along those lines. I'm interested in the trial to see if its worth upgrading and if there are any compatibility problems.
