Alternatively you can try replacing the following in your templates index.php (../templates/[YourTemplate]/index.php)...
<div id="container_hornav" class="j51container"><div class="wrapper960">
<?php require("php/layouts/hornav.php"); ?>
</div></div>
<?php if ($this->countModules('showcase')) { ?>
<div id="container_slideshow" class="j51container"><div class="wrapper960">
<?php require("php/layouts/slideshow.php"); ?>
</div></div>
<?php }?>
With...
<?php if ($this->countModules('showcase')) { ?>
<div id="container_slideshow" class="j51container"><div class="wrapper960">
<?php require("php/layouts/slideshow.php"); ?>
</div></div>
<?php }?>
<div id="container_hornav" class="j51container"><div class="wrapper960">
<?php require("php/layouts/hornav.php"); ?>
</div></div>
