I'm not familiar with that program but you do have options! It also depends on your use of the word "erase".

1. Did you actually erase or delete the name? Also most programs *backup* your data before you exit. Find that backup and restore.

Chances are the erased persons parents and any of that persons ancestry, on his side, are still there, in the database, but Unlinked to the erased person's spouse and children. In that case, Find the spouse, add the erased person, then find the erased persons parents and link the erased person to their parents. If that can't be done, find a program that can create a Gedcom. Once you get your tree back up to snuff, Backup your tree Often.

2. Go to ancestry.com and download your tree as a Gedcom. To do that....
On Your ancestry home page is your tree name. To the right of your tree name should be an option *View My Trees*. Select that option and a drop down window appears. Select the last option *View All My Trees*. A box appears with your main tree name. Under that tree name is 2 options. Select *Manage my Tree*. A new page appears. In the right bottom of the page is a button *Download my Tree*. select that option to generate a Gedcom. Then import your gedcom into your *NEW* genalogy program.

Most Genealogy programs use a Gedcom aka GEnealogical Data COMmunication format to share data with other genealogy programs. It's just a simple text file with some special characters that lets the other genealogy programs interpret your Gedcom when you import your data to another program.

If you are using Family Origins 6.x, it was probably using Gedcom 5.5 or earlier specification, released in Jan 1996.

Did you by chance print the users manual?
