Thanks for responding Andy. No I wasn't trying to access records not available for the weekend, I couldn't even get that far.
I sent them an email on Saturday, and just got a reply now (Monday in Australia). I had to sign in
first apparently, but the email I received originally just directed me to 'Start Searching', so that is what I tried to do. I've never had a subscription to Ancestry, I just receive these occasional free weekends.
Anyway, they've given me a password to use now, so I had better make good use of my remaining 15 hours.
Thanks to all who responded
Cheers
Kerry
