Problem with corpo theme

hy!

i am trying to implement the great plugin, but even when the checkbox is checked it returns:
Achtung: Du hast die datenschutzrechtlichen Hinweise nicht akzeptiert.

using wordpress 3.5.2 wiht CORPO theme.

here is my complete comments.php from that theme. I pasted the necessary line at the end, but also tried to put it into the array.

<div id="comments">

	<?php if (post_password_required()) : ?>
	<p><?php _e( 'Post is password protected. Enter the password to view any comments.', 'corpo' ); ?></p>
</div>

	<?php return; endif; ?>

<?php if (have_comments()) : ?>

	<h2><?php comments_number(); ?></h2>

	<ol class="commentlist">
		<?php wp_list_comments('type=all&callback=corpo_comments'); // Custom callback in functions.php ?>
	</ol>

    <?php if ( get_comment_pages_count() > 1 && get_option( 'page_comments' ) ) : // are there comments to navigate through ?>
		<div class="wp-pagenavi">
			<div class="alignleft"><?php previous_comments_link( __( '← Older Comments', 'corpo' ) ); ?></div>
			<div class="alignright"><?php next_comments_link( __( 'Newer Comments →', 'corpo' ) ); ?></div>
		</div>
    <?php endif; // check for comment navigation ?>

<?php elseif ( ! comments_open() && ! is_page() && post_type_supports( get_post_type(), 'comments' ) ) : ?>

	<p><?php _e( 'Comments are closed.', 'corpo' ); ?></p>

<?php endif; ?>

<?php 

    comment_form(array(
        'comment_notes_before' => '',
        'comment_notes_after' => ''

	)
    ); 

?>
                <?php do_action( 'akismet_privacy_policies' ); ?>

</div>
