I found a program to ecport Personal Roots 2.0 to a standard GEDCOM file. It was written by the original author of P.R.
First go here:http://www.saintclair.org/ftp/pub/pafutils/?S=A
In the list look for prged20.zip
I have not tried the software yet so I have no information as to its ability to really work. It should be fine, but run at your risk.
