Sidebar pushed to bottom

I recently installed the ‘Now Reading Reloaded’ application and when I click on a book title to view a single entry (same for Library and author list) the sidebar gets pushed to the bottom. I’ve tried everything I can think of, I just can’t seem to get the sidebar to load on the right where it should be.

My themes ‘page.php’ file looks as follows

<?php get_header(); ?>
<div class="contentLayout">
<div class="content">

<div class="Block">
  <div class="Block-body">

<div class="BlockContent">
  <div class="BlockContent-body">

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
    <div class="post" id="post-<?php the_ID(); ?>">
        <h2><?php the_title(); ?></h2>
        <div class="entry">
	        <?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?>
		    <?php wp_link_pages(array('before' => '<p><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?>
        </div>
    </div>
<?php endwhile; endif; ?>
<?php edit_post_link('Edit this entry.', '<p>', '</p>'); ?>

  </div>
</div>

  </div>
  <div class="Block-tl"></div>
  <div class="Block-tr"><div></div></div>
  <div class="Block-bl"><div></div></div>
  <div class="Block-br"><div></div></div>
  <div class="Block-tc"><div></div></div>
  <div class="Block-bc"><div></div></div>
  <div class="Block-cl"><div></div></div>
  <div class="Block-cr"><div></div></div>
  <div class="Block-cc"></div>
</div>

</div>
<div class="sidebar1">

					<?php include (TEMPLATEPATH . '/sidebar1.php'); ?>

</div>

</div>

<?php get_footer(); ?>

For reading reloaded, single.php looks as follows:

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

<div class="content">

	<div id="content" class="narrowcolumn primary now-reading">

	<div class="post">

		<?php if( have_books(intval($nr_id)) ) : ?>

			<?php while ( have_books(intval(nr_id)) ) : the_book(); ?>

			<?php if( can_now_reading_admin() ) : ?>
			<p>Admin: &raquo; <a href="<?php manage_library_url() ?>">Manage Books</a> &raquo; <a href="<?php book_edit_url() ?>">Edit this book</a></p>
			<?php endif; ?>

			<?php library_search_form() ?>

			<p><a href="<?php library_url() ?>">&larr; Back to library</a></p>

			<h2><?php book_title() ?></h2>
			<p>By <a href="<?php book_author_permalink() ?>"><?php book_author() ?></a></p>

			<p>
				<a href="<?php book_url() ?>"><img src="<?php book_image() ?>" alt="<?php book_title() ?>" /></a>
			</p>

			<?php if( !is_custom_book() ): ?>
				<p>You can view this book's Amazon detail page <a href="<?php book_url() ?>">here</a>.</p>
			<?php endif; ?>

			<?php if( book_has_post() ): ?>
				<p>This book is linked with the post <a href="<?php book_post_url() ?>">&ldquo;<?php book_post_title() ?>&rdquo;</a>.</p>
			<?php endif; ?>

			<p>Tags: <?php print_book_tags(1) ?></p>

			<dl>
				<dt>Started reading:</dt>
				<dd><?php book_started() ?></dd>

				<dt>Finished reading:</dt>
				<dd><?php book_finished() ?></dd>

				<?php print_book_meta(0); ?>
			</dl>

			<div class="review">

				<h3>Review</h3>

				<p><strong>Rating:</strong> <?php book_rating() ?></p>

				<?php book_review() ?>

			</div>

			<?php endwhile; ?>

		<?php else : ?>

			<p>That book doesn't exist!</p>

		<?php endif; ?>

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

	</div>

	</div>

	<?php get_sidebar(); ?>

</div>

<?php get_footer(); ?>

Any help would be appreciated, thanks.
