IMDB Account - How to bring back content?

I originally saved my account via Facebook a few years ago and had to make changes to due personal device transfer recently. Unfortunately it instead created a brand-new blank account, which I didn't want to do. My information is still saved onto the site, but is there a way I can get full access back to the original account again? I did try logging back in multiple times, but it always seems to set-up a brand-new account over and over and over and over again. Instead of allowing to just log in - I had to sign in using something else. Is there any way I can fix this problem and get back access properly with all the stuff I saved onto the site (ratings and lists) through another way without restarting it by "Sign In"? Please let me know as soon as you can, Lewis McIntosh
