Same thing with page navigation on this template as well… I have no clue what I’m doing wrong or wtf I changed… Please help!

<?php
/*
Template Name: Blog
*/
?>
<?php get_header(); ?>
<?php if (have_posts()) : ?>

<div id="content">
    <!--page.php-->
<div id="post" class="post clearfix">
<div id="blog-heading"><h1>Blog &amp; News Articles</h1></div>

            <?php query_posts(array('paged' => get_query_var('paged'),'posts_per_page' =>10)); ?>
            <?php query_posts('cat=-3'); ?>
			<?php if ( have_posts() ) : while ( have_posts() ) : the_post();?>

	<!--post title-->
    <h2><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></h2>

	<!--post text with the read more link-->
<?php the_excerpt(); ?>

	<!--for paginate posts-->
	<?php link_pages('<p><strong>Pages:</strong> ', '</p>', 'number'); ?>

    <?php //comments_template(); // uncomment this if you want to include comments template ?>


	<?php endwhile; // end of one post ?>
<div class="page-nav">
<?php 	 wp_pagenavi(); ?>    </div>
	<?php else : // do not delete ?>
	<h3>Page Not Found</h3>
    <p>We're sorry, but the page you are looking for isn't here.</p>
    <p>Try searching for the page you are looking for or using the navigation in the header or sidebar</p>

    <?php
endif; // do not delete ?>

<!--page.php end-->
</div>
</div>
<?php endif; ?>
<?php get_sidebar(' '); ?>
<?php get_footer(' '); ?>
