• Answer:

  if you have forgotten the details of your account then you won't be able to receive a new password. *that guy didn't change the password! he only tried to guess and your account is locked up for multiple attempts. so the only way for you to recover is to remember all the info you entered when you created that account. hacking programs are not 100% effective. lol
