.watts. on "Next Posts button just repeats the latest 8 posts"

I'm hoping someone can help me sort out a navigation issue I'm having with my website at SevenSharks.com

When I first designed my site, It had a custom static front page that was blank like a gateway page. I recently deactivated that page, and made the blog page the static front page. After making the change, my pagination stopped working correctly.

Clicking "Older" now only loads the same 8 posts (the 8 most recent posts) instead of cycling backwards through older posts.

Its really driving me crazy.

Here is the only relevant code as far as I know:

<?php
    /**
     * For get looping of blog.
     */
    $paged    = (get_query_var('paged')) ? get_query_var('paged') : 1;
    $args     = array(
            'orderby' => 'date',
            'order' => 'DESC',
            'paged' => $paged,
    );
    $temp     = $wp_query;  // assign orginal query to temp variable for later use
    $wp_query = null;
    $wp_query = new WP_Query($args);
?>

	 <?php get_template_part('loop'); ?>

<?php $wp_query = $temp; wp_reset_postdata(); ?>
