I take the lack of response to my cry for help as an indication that I really did a bad one.
Fortunately, I appear to have lucked out. I had crashed the computer with DX4WIN open just before I wrote all those QSL dates, and the backup file only had 3 more QSOs than its predecessor. I had renamed the backup file and was using it when I screwed up, so I was able to revert to the previous one, manually add the 3 QSOs, and I'm good to go again. 73, Pete N4ZR Sometimes a tower is just a tower
