Linked Facebook with old Email Address 3000 Ratings from 2012

I've had my account since 2012 and rated almost 3k movies with various other activity - I'm on IMDB.com more than any other site!

I'm really nervous because I have an account linked to Facebook with an old, inaccessible email address. How can I change me email address and password? I'm really worried I'm going to lose the 1000s of hours of the work I put into my account.

Happy to pay or upgrade my account? Whatever it will take. Thank you!
