Change Facebook linked email

I signed up a long time ago via Facebook when I had a live.com email which is long forgoten today and is changed on Facebook as well.

My original ID is markolitre and I am still logged in on the site. But I cannot change the email. When I try I'm asked to login via the live.com email.

How can I change my login email and password on IMDB since I do not have the live.com email anymore?
