Pagination issues on Custom Post Types – 404 pages

Hi,

So I can’t seem to get pagination to work on my templates and its making me batty. I have a piece of code I’ve used for ages with no issues except for now, it seems to not work with post-types. I get a 404 error when i try to go to page two.

Any suggestions?

<?php 

		// pagination
		$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

		// query
		$listings = array(
		'post_type' => 'event_listing',
		'meta_key' => 'tf_events_startdate',
		'orderby' => 'meta_value',
		'order' => 'DESC',
		'posts_per_page' => 2,
		'paged' =>$paged

		);
	?>

	<?php query_posts($listings); ?>
	<?php if (have_posts()) : while (have_posts()) : the_post();?>

<?php the_title();?>

<?php endwhile; else: ?>
	 <p><strong><?php include('inc/nope.php');?></strong></p>
	<?php endif; ?>

	<div class="postNavigation clearfix">
	 <p class="postNavL"><?php next_posts_link('« Older Entries') ?></p><p class="postNavR"><?php previous_posts_link('Newer Entries »') ?></p>
	</div> <!-- end .postnavigation -->

<?php wp_reset_query(); ?>
