404 error when try open admin login

Your url is loading the domain hosts standard parked domains page. Have you configured the DNS for your domain and pointed it at the server which is hosting your site. If you are having issues with this you’ll need to contact your webhost.

@fscu – see: http://codex.wordpress.org/Resetting_Your_Password

You WILL need to have access to your site files on the server or the database – ask your hosting company for help, if you don’t have it set up.
