Hi Sam
If your "old" tree contains any media files then you may be unable to upgrade directly.
You may need to upgrade in more than one hop if media files are involved.
Start with a few (more) questions . . . . .
1) Is the old computer system still with you? Still working?
2) Make / model of computer system? Windows? What version?
3) The tree data is still on the computer systemit? More than one tree?
4) Exact name of tree program? Version number?
(Start it up, go to "Help", the name/version may very well be there.)
Regards
Ray
