I purchased MacFamilyTree for $25. Now I'm asked to enter a previous serial. What do I do?

The version you purchased is the update license. Only owners of a previous version of MacFamilyTree can upgrade at this discounted price. This is our way of saying thanks for ongoing support of our software development efforts. If you don't own a previous version of MacFamilyTree, please purchase a second upgrade license. Since the update is 50% off the regular retail price, you'll pay the same as if you had purchased the full version in the first place.

After that, please contact our support team and forward both orders to us. We'll send you one full version serial as a replacement.

More general information is available in the User Guide. You can find it in MacFamilyTree's Help Menu or for download here.
