Cant register

So i wanted to log in today and it wrote my password is older than 6 months, i tried changing and when i got the link to my gmail and opened it and tried changing password, it wrote that the addres from where i got this link is not correct (or something like that). So then i tried registering a new account and it wrote that i already got an account, then i went to that link that they send me (for password recovery) and there i found an unsub link and i tried it and i still cannot register a new account, please help!
