So I have a file that is. "Popa" in place of a GEDCOM. Ancients used to link with another company before coming to Family Tree Maker and offered a free version. Can not find a program running. Does anyone have a configuration file for the former haunt or know what is going to run a. Popa?

Family Tree Maker 2005 and Family Tree Maker 16 (the two most recent versons Family Tree Maker) is The file opens.
