You're probably using the wrong password. You can use this page to set up a new password
https://www.heliohost.org/password/
Please be aware that the page will only securely submit the password to us, so the new password won't work until I manually assign it to your account. Your plaintext password will never be visible to me or anyone else. Once you have submitted the new password let us know and we can update your account. Since cPanel doesn't work anymore you can't change your password yourself directly so I created this page as a work around.
