All lists are gone

Since the option of Logging in with Facebook has been disabled, I discovered I already had an account with only 1 watched item saved. It had no lists, nothing.

The thing is: fot both accounts I apparantly use the SAME emailadress, but I always used the 'login via Facebook' option so that's the one which is updated.  I tried everything to recover my 'facebook-page' but no matter what I do, I keep ending up at the one with only 1 saved item. All I want is to have all my lists back, so I could really use some help.
