Custom Post Type Not Working

my site is located at https://beta.limelightmich.com

I currently have 3 custom post types.
1) News
2) Projects
3) Services

news and projects pull a page just fine but for some reason, clicking on any of the services gives you a “not found” error. Can anyone tell me why this might be happening? Using WP 3.1.2. My code is below. Any help would be appreciated!!!

add_action( 'init', 'create_post_type' );
function create_post_type() {
	register_post_type( 'News',
		array(
			'labels' => array(
				'name' => __( 'News'),
				'singular_name' => __( 'News' ),
				'add_new' => __('Add News Article'),
				'add_new_item' => ('Add News Article'),
				'menu_name' => ("News")
			),
		'public' => true,
		'menu_position' => 5,
		'has_archive' => true,
    	'supports' => array('title','editor','author','thumbnail','comments')
		)
	);
	register_post_type( 'Projects',
		array(
			'labels' => array(
				'name' => __( 'Projects'),
				'singular_name' => __( 'Project' ),
				'add_new' => __('Add Project'),
				'add_new_item' => ('Add Project'),
				'menu_name' => ("Projects")
			),
		'public' => true,
		'menu_position' => 5,
		'has_archive' => true,
    	'supports' => array('title','editor','author','thumbnail','comments')
		)
	);
		register_post_type( 'Services',
		array(
			'labels' => array(
				'name' => __( 'Services'),
				'singular_name' => __( 'Service' ),
				'add_new' => __('Add Service'),
				'add_new_item' => ('Add Service'),
				'menu_name' => ("Services")
			),
		'public' => true,
		'menu_position' => 5,
		'has_archive' => true,
    	'supports' => array('title','editor','author','thumbnail','comments')
		)
	);
}
