I have Merlin. :) On the disk it just says Merlin Pro. I called Roger Wagner Publishing just the other day and ask if there were any upgrades. The lady on the phone said that Merlin 8/16 was their last upgrade. You can call and talk them your self. 1-800-421-6526 They are sending me a catalog so I can see what they have that I wont. Maybe they can do the same for you. :)
