If it's been disabled, someone has reported it stolen. or used Find My iPhone to disable it. In case 1, if you bought the device, get your money back and report it to the police. In case 2, you've got other equipment also using your Apple ID. If you've got a Mac, you should be able to find the information you need in Keychain Access.app.

If your Apple ID had an easy to guess password, it's possible someone else logged in and disabled your password. If this is the case, you're going to have to take this up with Apple directly, and get them to reset your Apple ID and give you a new password. To do that, you'll have to have proof that you are the original owner of the account, so you'll need your Apple ID account name or email address.
