How do I upgrade a version 4 family file?

You need to send us your version 4 family files.

Actually, in version 4, a "family file" was really a folder, with a name something like "Clinton Family File" or "My Family File." Inside that folder is a collection of similarly named files, for example...

Select that folder in the Finder (the folder containing those similarly named files) and choose File > Compress.

Then attach the resulting .zip file to an email message and send to help@LeisterPro.com

We'll convert the files ASAP.
