LONG TIME REGISTERED USER

I am a long time registered user of this product. I noticed recently that my license didn't seem to be valid any longer. I wasn't even able to get an update...."unable to connect to server".

Went to site & discovered new version which I downloaded/installed. How do I confirm I'm still registered. I paid for this years ago but to be honest don't remember where I stored the info. I have since added my new email address & don't use the old address too much anyone. Am I still a registered user.
