GSP Family Tree is pretty ancient to say the least, it dates back to the 1990s, I think the last version might have worked in Windows XP. It seems to have morphed into GSP Who Do You Think You Are Family Tree Maker which was aimed at ME, XP & Vista. This now seems to have become Avanquest WDYTYA Family Tree Maker which does not match the original very well.
You may have to look at new family history software. Family Tree Maker is one option, I use Family Historian and there are others. There are a number of threads on the forum about choice of software which are worth reading. GSP FT should be able export your data as a Gedcom file which is readable by most modern family history programmes
