There are two possibilities if any AOL user doesn’t use any email within 6 months, it counted as inactive accounts. The server put those accounts in disable mode.
If the user is not trying to reach their accounts with few months after disabling, the server has rights to remove that accounts and data permanently.
It might possible your AOL account is on disable mode also you are not able to reset your password.
So would like to suggest you contact your email service provider and enable your account as soon as possible.
