Hi There

Im having issues getting the pagination to work on this loop. As soon as it goes to page 2 I get a 404 error saying page not found.

<!-- we begin the loop -->

<?php
global $query_string;
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts($query_string.'&paged='.$paged.'&posts_per_page=4');
?>
<?php if (have_posts()) : ?>
<?php $count = 0; ?>

<?php while (have_posts()) : the_post(); ?>
<?php $count++; ?>
<?php if ($count == 1) : ?>

<!-- First article which displays differently to the rest -->
<!-- wp article stuff will go here -->

<?php else : ?>
<!-- the rest of the articles will go here -->

<?php endif; ?>
<?php endwhile; ?>

<?php cfct_misc('nav-posts'); ?><!-- this is the pagination -->

<?php else : ?>
<!-- this is where the info will go if no posts are found -->

<?php endif; ?>
<!-- Finally we end the loop -->

Im hoping someone can help? Ive searched everywhere for a solution
