Domain error

Hi,

I recently cancelled mapping my domain to WordPress.com. I have pointed my domain to my host.

But now when I try to go to wp-admin/index.php I get this:

Warning! Domain mapping upgrade for this domain not found. Please log in and go to the Domains Upgrades page of your blog to use this domain.

And when I go to my front page:

<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . ‘/wp-blog-header.php’ );
