I tried to check the old web site that had the information on version 3.0, Dick, but it has been taken off. Unfortunately, our old RUG newsletters that I quickly browsed through, did not have the "fixes" listed. I'm sure it's somewhere, though. You may be hard pressed to find version 3.0 since it's been discontinued, though. Some of the not-so-well-known office stores may have an old copy ... you'll have to do some phoning around probably. Best of luck to you.
I would say your best bet if you want to upgrade at all would be to go to TMG (The Master Genealogist) www.whollygenes.com You can easily transfer all of your data via TMG's GenBridge program that is included with the product, so you don't need to use the GEDCOM and lose data.
