OK. Before hit the bed, logged on from MacBook. Looked like though I had logged on earlier from MBA, it did not remember my log-in credentials on the browser. When tried logging in, first instance, it gave me a message to say "Could not log in" . It took a few minutes for me to figure out, I had omitted one letter in my email address in the log in field. I'd thought, why didn't it just say something like 'incorrect email address' ….?
