I can't login with Facebook or reset password

​I used to use Facebook to login into IMDb, but I cannot reset my password either using the technique recommended. I go to the reset password page, type in my email and the captcha, and there is always an error.​

​The email is definitely correct because it's the one I use for Facebook. When I login using my Google account, obviously all my watchlist and old rankings are not there. I've literally got like a thousand rankings and 200 films in my watchlist, which I can't remember off the top of my head, so this is really irritating. ​

​Bizarrely, I am still logged in on the IMDb app on my Samsung, but I can't double check any details like my email address or do anything from there.​

​How can I recover my account and my watchlist etc?​
