Thanks Bruce & Douglas

I tried the re-build at the time I did the data integrity check - it didn't fix the problem, and the next D.I. check stopped at the same point.

I'd be willing to bet dollars to dimes that there is a background file that needs to be deleted so the program can recreate it. We had a similar problem last year with my financial statements, where the sets I had created seemed to have disappeared. When my re-seller came in (& called Softrak Tech support), the fix was quick & easy - delete the file and the program recreated it - all was well.
