I'm going to guess that TT "pushed" an update to me. Don't know how that works, but this time when I opened TT, it downloaded a couple of updates, and eventually ran for me. I've been able to transfer last year's file to this year, and make some this year entries, and save. So I'm happy at this point.
For the record, I did a direct download from Intuit, not from Amazon or another source, or from a CD. I've been using TT for probably 20 years, so I have a clue what I am doing. Thanks to all for the help!
