What is the error you are receiving? I can see cpanel is working on your server. If you are getting a "cannot connect" message, make sure that you are not behind a firewall blocking the ports. If it is an invalid password message, make sure you are using the correct username and password.

Channing your password on the forums will not effect your hosting account.
