Thanks for your advice and ideas. I do have backups on Time Machine that are available but only back about 2 months and have tried them. I think the file was bad prior to that. It was strange that it didn't show up in the old software but did in the new but, oh well. I haven't tried all of your suggestions yet but did take the old software off my computer yesterday and have made a little progress since then. I was able to get a file from Ancestry copied to a different computer and transferred it to my own in the new software and it looks workable. Need to look at that more closely today. I'll keep the rest of your ideas in my back pocket for the next things to experiment with- should the need persist. Thanks so much!!!
