After downloading v1.4, 1.6 and 1.7 I can say the most current dates on the zip files are on v1.6. I don't remember where I downloaded v1.4, but 1.6 and 1.7 came from PBW. There's just to many ship sets to look through and a couple of web sites that carry some of each. It's a very confusing situation out there!
Thanks for all your help.
