I can access it now too.

My guess is the date format has been changed on the system, resulting the dayfile using different a date string in the past from now.

Mark,
As always your help is invaluable.
I reviewed dayfile.txt and the recorded date was in the format DD/MM/YYYY from inception (10/2018) until Jan 2021. Then it switched ?
Don't know why and whether I had a hand in it by doing edits at some point. Lets blame me.
Anyway, changed all dates to YY and it's working fine.

Many thanks,
Peter

Sounds typical of the sort of error introduced by opening the file in something like Excel then saving it.
