If you have not logged in to your Apple account for some time, you may have forgotten your password, and maybe even your username! You can resolve this by resetting your account then by answering security questions or by using an alternate email address then if necessary, doing an upgrade. The more information you can provide, the easier it will be to log back into your Apple account.
