I’m away from home, with only a mobile router, so I attempted the downloads at
our son’s house. TalkTalk, my service provider, won’t let me send email from
my laptop using his router, so perhaps it’s stopping the validation, but only
after using up a GB or two of his service! Virus-checker (etc) Avast didn’t
seem to be involved; it was happy with the downloaded files.
I’ll try again next week.
Thanks,
Mike
