Shortcodes not working with get_extended()

Hi,

I’m currently separating the before and after <!–more–>, so I can use CSS on specific parts in text.
However when a shortcode is added in content, this is just printed out and not “activated”.
This is how my template looks like with printing the content.

$the_content = get_extended($post->post_content);

$main = $the_content['main'];
$content = $the_content['extended'];

<?php if (!empty($content)) : ?>
  <div class="main">
    <?php echo wpautop($main, true); ?>
  </div>
<?php endif; ?>
  <div class="content">
  <?php if(!empty($content)){
    echo wpautop($content, true);
  } else {
    echo wpautop($main, true);} ?>
  </div>

Any suggestions for how to overcome this?
