adding adsense after 1st post on frontpage

I am trying for some time to add a adsense block after the 1st post on the frontpage.

Now I have looked on the internet how to do it and they didnt work.

I also tried to use plug in such as ads easy, ad injection and frontpage banner.

So far non of them works.

I am using the NewsMagazine Theme and my page.php looks as follow:

<?php global $theme; get_header(); ?>

    <div id="main">

        <?php $theme->hook('main_before'); ?>

        <div id="content">

            <?php $theme->hook('content_before'); ?>

     <script type="text/javascript"><!--
google_ad_client = "**************";
/* _ */
google_ad_slot = "********";
google_ad_width = 468;
google_ad_height = 15;
//-->
</script>
<script type="text/javascript"
src="https://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
            <?php
                if (have_posts()) : while (have_posts()) : the_post();
<?php $count = 1; ?>
                    /**
                     * Find the post formatting for the pages in the post-page.php file
                     */
                    get_template_part('post', 'page');

<?php if ($count == 1) : ?>
<script type="text/javascript"><!--
google_ad_client = " ";
/* textblok */
google_ad_slot = " ";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="https://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
<?php endif; $count++; ?>
                    if(comments_open( get_the_ID() ))  {
                        comments_template('', true);
                    }
                endwhile;

                else :
                    get_template_part('post', 'noresults');
                endif;
            ?>

            <?php $theme->hook('content_after'); ?>

        </div><!-- #content -->

        <?php get_sidebars(); ?>

        <?php $theme->hook('main_after'); ?>

    </div><!-- #main -->

<?php get_footer(); ?>

I hope someone can tell me how to add the adsense after the 1st post.

ps. the first adsense code is for a horizontal banner above the 1st post which is working.
