I bought this product when I upgraded to windows 7 earlier this year. I have over 400 years of family history on GSP Family Tree Windows XP but this is not compatible with Windows 7, hence the need to buy an upgrade. I now find that I can not import my original "tree" to the new version because the whole format is different and I get a promt telling me that the GEDCOM files I try to import are out of date. I am left with the choice of losing everything previously saved or starting from scratch with the new version. One question keeps bugging me, If I save everything to the new GSP Family Tree will the same thing happen when the next upgrade comes along?
