Can't login to Facebook, invalid e-mail address

[CW1]

Hi,
Had an e-mail from Facebook from someone I'd been trying to find but when I try login, it's not accepting my password. Go to 'Forgotten your password?' and it comes back with error
'Invalid Email Please check the email address you entered. If you added multiple email addresses to your account, you can use any one of them to request a reset link.'
It's the same e-mail address they sent the e-mail to ! I can't find any way of contacting Facebook about this - anyone know a way ?
