Custom Thumbnail PHP from previous version now not working

i was using the previous version of YARPP with the following custom template:

<br><br><div class="related_posts">
<h2>If You Liked This, Check Out:</h2><br>
<?php if ($related_query->have_posts()):?>
<ul>
    <?php while ($related_query->have_posts()) : $related_query->the_post(); ?>
        <?php if (function_exists('has_post_thumbnail')): if (has_post_thumbnail()):?>
	<li>
	    <div class="related_thumbnail">
	        <a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(array(150,150)); ?></a>
	    </div>
	    <div style="clear:both;"></div>
	    <div class="related_permalink">
	        <a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>
	    </div>
	</li>
	<?php endif; endif; ?>
    <?php endwhile; ?>
</ul>

<?php else: ?>
    <p>No related photos.</p>
<?php endif; ?>
</div>

this was titled yarpp-template-thumbnail.php

everything worked perfectly. since the upgrade, though, now only the <h2> title appears – no images, no text.

I’m using Headway version 2.0.14. and here’s my site: http://www.nonstopawesomeness.com (YARPP available on single post pages).

i’m pretty simple when it comes to code – i can copy/paste, but i don’t know how to write php files.

thanks for any help!
