A problem has occurred today. When I opened Cumulus 'New Record' was flashing. All the following were showing -

L.Temp- -26.3; Wind Chill - -26.3; Apparent- - 30.2; Dew - - 31.3; High D.Temp - 30.1; H. Wind Gust - 51m.p.h.

All occurred at the same time 22.22hrs 11 Feb.

All current readings as I am writing are correct. Any advice?

Thanks in anticipation.

You've had one of the infamous Fine Offset 'spikes'. You can get Cumulus to ignore these using the spike removal settings on the calibration screen. The easiest way to reinstate your previous highs and lows is to copy the month.ini, year.ini, and alltime.ini from a recent Cumulus backup (with Cumulus stopped). You'll probably have some other correcting to do in your Feb log file and fayfile.txt.
