cant open an account through fb


Hi Nathan,
That message indicates that you created another account using your Facebook ID, which you have since closed - hence when you try to log in using Facebook, it tells you that "this account has been disabled". Unlike e-mail addresses (which get unlinked when you close an account so the same e-mail address can be linked to a new account), Facebook profiles don't get unlinked.
Ordinarily this means you would need to contact the Support team via Help --> Support and they would help you out, but I might be able to help - can you please try again and see whether you can now log in to this account using Facebook?
