That’s the downside of changing email addresses. You’ve probably already tried this, but run through the login with all the passwords you might have used.
You could try to contact AOL customer service, but I have NEVER received a reply from them on ANY of my email messages. But there’s a first time for everything. Maybe you’ll get lucky. Be prepared to provide some proof of identify and ownership of the old email and screen name, and as Rustedtight said, don’t expect much. They’ll probably say “no.”
In the future, it wouldn’t hurt to write down the passwords (and the corresponding email addresses) in a safe place.
