Slider Not Working

Downloaded a theme and can not get my slider to work. I have 4 slides published, but only one shows.

This is the Slider.php code…please help me ASAP. Thanks!

<?php

$slide_settings = get_option('ct_slide_settings');
$orderby = $slide_settings['orderby'];
$order = $slide_settings['order'];
$tags = $slide_settings['active_slide_tags'];
$num = $slide_settings['slide_limit'];

if(empty($orderby)): $orderby = 'date'; endif;
if(empty($order)): $order = 'DESC'; endif;

global $post;

if($orderby == 'views'):
	$args=array(
		'post_type' => 'slide',
		'post_status' => 'publish',
		'posts_per_page' => $num,
		'meta_key' => 'Views',
		'orderby' => 'meta_value_num',
		'order' => $order,
		'slide_tag' => $tags,
	);
else:
	$args=array(
		'post_type' => 'slide',
		'post_status' => 'publish',
		'posts_per_page' => $num,
		'orderby' => $orderby,
		'order' => $order,
		'slide_tag' => $tags,
	);
endif;

$query = null;
$query = new WP_Query($args);
