AVG "Confirm My Email" message going to old email acct

I completed a purchase of AVG Driver Updater and received the instructions that include confirming my email. The message indicates an old email address was used. I cannot access that email at all. Haven't had that address for two years. My correct email is listed on my AVG account. How can I get the old email to stop showing up for AVG's selection for confirmation messages?? Thanks. Really more of a question for AVG techs than whole community, but anyway…
