Posts not showing up on blog posts page

I want to set up a static front page so I changed my posts page to “blog” but when I go to the URL I get the following error message

Index of /blog

* Parent Directory

Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8i DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at theinternetmarketingresourceguide.com Port 80

The URL is http://theinternetmarketingresourceguide.com/blog/

I have published posts. WordPress is installed in the root directory. I have not changed the front page to the static “home” page yet because I have not designed the page yet. I have changed the permalink structure to /blog/%postname%/

The page.php code is:

<?php get_header(); ?>

	<div id="content">
	<div class="entry">
		<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
		<div class="post" id="post-<?php the_ID(); ?>">
		<h2><?php the_title(); ?></h2>

				<?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?>

				<?php wp_link_pages(array('before' => '<p><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?>

			</div>
		</div>
		<?php endwhile; endif; ?>
	<?php edit_post_link('Edit this entry.', '<p>', '</p>'); ?>
	</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

The index.php code is:

<?php get_header(); ?>

	<div id="content">

	<?php if (have_posts()) : ?>

		<?php while (have_posts()) : the_post(); ?>
<div class="entry">
			<div id="post-<?php the_ID(); ?>">
				<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
				<abbr title="<?php the_time('Y-m-d\TH:i:sO'); ?>"><?php unset($previousday); printf(__('%1$s – %2$s'), the_date('', '', '', false), get_the_time()) ?></abbr> <!-- by <?php the_author() ?> -->

					<?php the_content('Read the rest of this entry &raquo;'); ?>

				<p class="postmetadata">Posted in <span class="cty"><?php the_category(', ') ?></span> | <?php edit_post_link('Edit', '', ' | '); ?>  <span class="cmt"><?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></span></p>
				</div></div>

		<?php endwhile; ?>

		<div class="navigation">
			<div class="alignleft"><?php next_posts_link('<span class="prev"> Previous Entries</span>') ?></div>
			<div class="alignright"><?php previous_posts_link('Next Entries <span class="next">&nbsp;</span>') ?></div>
		</div>

	<?php else : ?>
<div class="entry">
		<h2>Not Found</h2>
		Sorry, but you are looking for something that isn't here.
</div>

	<?php endif; ?>

	</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Any ideas on how to get posts to show up on the posts page?
