Sgouver on "[Theme: Pilot Fish] Cant place the Multisite Language Switch flags at the site's top right corner."

I want to add the Multisite Language Switcher flag icons on the top right side of the header in my site.

My Site is: http://3dtours.gr

The step I have made so far is:

Adding successfully at my functions.php the code :

// Create a widget region for the
// Multilingual Press lang switcher
///////////////////////////////////////
if ( function_exists('register_sidebar') ) {
	register_sidebar(array(
		'name' => 'Language Switcher',
		'id' => 'language-switcher',
		'before_widget' => '<div>',
		'after_widget' => '</div>'
	));
}

Now I have a Widget devoted for the Multilingual Press lang switcher but when I try to add the :

<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Language Switcher') ) : ?>
<?php endif; ?>

in Header.php the language flags are not correctly placed at the top right corner of the site.

If you could give me any advise to solve this problem I would be grateful!!!
