Ashik, many thanks for your very comprehensive answer.
Actually, I didn't reset any password, so not sure what happened there.
I will follow your instructions to restore from my iTunes backup, and report back to you tomorrow (Monday).
I'm still working on this, and will report back tomorrow, as I may have some questions.
Ashik, this worked fine - many thanks for your help.
