Thanks Doug
I copied (or perhaps moved and renamed by mistake) the rumlog adi file to the same directory as the original wsjtx_log.adi
and renamed the old one.  The old one had all the qsos from this year only.  I thought the rumlog would be complete...now I see ZERO worked-before when I rescan ADIF log.  However in Band Activity, I still see blue highlighting on new calls.  How can that be?
Should I just start over?  did I lose my >10 years of logging?
