Older Entries showing same as page 1

on my site the only blog posts it shows when you click older entries is the same as it shows on the first page. Done a ton of searching, think i know where the problem is (posted below) but not sure how to fix it.

I have the same problem with the free version and the premium and their tech support is not responding. Any help would be greatly appreciated

<div class=”pagination”>
<?php if($GLOBALS[‘wp_query’]->max_num_pages > 2) : ?><div class=”separator”></div><?php endif ?>
<?php posts_nav_link(‘ ‘, __(‘Newer Entries’, ‘pitch’), __(‘Older Entries’, ‘pitch’)); ?>
<?php if($GLOBALS[‘wp_query’]->max_num_pages > 2) : ?><div class=”clear”></div><div class=”separator”></div><?php endif ?>
</div>
