Password invalid

When I tried to access one of my blogs on www.remarpro.com, I gave an invalid password. I asked for a new password, I was sent an email with the link to change the password and the 6 times I tried to validate, the answer was always this: Enter your username or email address. You will receive a link to create a new password via email.
