Thank you for kind words - yes, I am knocking on wood every day! 
I did not notify AIMA of my address change. They must have gotten it from Portal das Finanças. That was impressive… until I realised that my card was issued with my wife’s NIF number on the back! Jolly good!!! How am I going to change it now???
Oh well, at least I have a card to flash at the border control next time I travel in and out of EU.
