Dear Listers, I know that v5 is the latest. Q1 - Does the older version 3.1 and/or 4 work with windows 8? I have just purchased a laptop which runs windows 8. I have saved my tree,branches and related pics etc on to a memory stick from my old computer. Q2 - If Q1 is No and I have to upgrade to 5 to work with windows 8 can I still copy over from my memory stick the tree etc even though it was done on v3.1. As its a large tree I don't want to risk losing anything. Q3 - V4 is it just a case of purchasing an upgrade to V5 as opposed to the full V5. Much thanks in advance. Kind Regards Cheryl.
