I have been creating a new log each year (though I'm still using Log17 here in April 2018...). When I try to "Open new log" (from the "new QSO" window) and select, say, Log14 to see my 2014 QSOs, the "new QSO" window shows Log14 at the top but, as expected, the QSO list window is blank. I used to open these previous-years' QSO lists, though I don't remember the method, but am now finding that choosing either "Show QSO list" from the "New QSO" window, or "Refresh data" from the blank QSO-list screen, produces this error message:
qCQRLog: Field not found: "id_cqrlog_main"
Press OK... or Abort...
Advice on how to access all of this older data? CQRLog 2.2.0-001, Kubuntu 16.04.
PS: Thanks for your reply, Saku!
