Code not working after installing this plugin

I am running a custom loop that worked fine until installing this plugin. If I disable the plugin then my code begins working just fine.

It appears the issue has something to do with the $i variable and counting posts. Could you give my insight into why this plugin would conflict. My code is pasted below

<div class="slides">
			<div class="slide">
						<?php query_posts('showposts=8&cat=263'); $i = 1; ?>
				<?php while (have_posts()) : the_post(); ?>
<?php if( $i %5 == 0 ) { echo '<div class="slide">'; }; // open div ?>
					<div class="box">
						<h6><a href=""><?php the_field('kicker'); ?> ></a></h6>
					<?php if (has_post_thumbnail( $post->ID )): ?>
                <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' ); ?>
                <img src="<?php echo get_template_directory_uri(); ?>/timthumb.php?src=<?php echo $image[0]; ?>&w=230&zc=1" />
				<?php endif; ?>
						<h4><a>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h4>
						<p><?php the_advanced_excerpt(); ?></p>
						<p><a>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">Read More</a></p>
					</div><?php if( $i %4 == 0 ) { echo '</div>'; }; // open div ?><?php $i++; endwhile; ?>
		</div>
