Displaying more than 10 upcoming events.

I've done my research on these boards, but haven't found a successful solution. I'm simply trying to display at least the next 20-30 upcoming events (I realize there are current limitations on this with the plugin).

My catch is that I'm only seeing 10 upcoming events. I would be happy if I could have 20-30 even if it's a hack for the time being. Any suggestions? Below is my code on my template page:

<?php query_posts($query_string . '&orderby=date&order=ASC'); ?>
						<?php if (have_posts()) : while (have_posts()) : the_post();?>

						<div id="event-post">
						<h2 class="posttitle"><?php echo get_the_title($ID); ?></h2>

														<?php the_content(); ?>
												</div>
														<?php endwhile; endif; ?>

I have alternatively tried this code instead (found in another thread), but still I only get 10 events listed:

<?php query_posts( array( 'post_status' => 'publish' , 'post_type' => array( 'incsub_event' ) , 'meta_key' => 'incsub_event_start' , 'orderby' => 'meta_value' , 'order' => 'ASC'   ) ); ?>

												<?php if (have_posts()) : while (have_posts()) : the_post();?>

												<div id="event-post">
														<h2 class="posttitle"><?php echo get_the_title($ID); ?></h2>

														<?php the_content(); ?>
												</div>
														<?php endwhile; endif; ?>
