I need some help figuring out why the drop down menus are not displaying in my theme, I have hard-coded this menu in several other C5 sites and have never had this problem before and I can't figure out why. I have the navigation setup the same way as the other sites just customized the colors to fit theme.

The only difference with this site is that when I installed C5 I chose "Sample Content" to include the blog that's the only difference, is there something different that needs to be done when hard-coding the navigation when including the blog as oppose to choosing "Empty Site"? Any help would be much appreciated.
Here is the code for the nav block
[
<?php
$bt_nav = BlockType::getByHandle('autonav');
$bt_nav->controller->displayPages = 'top';
$bt_nav->controller->orderBy = 'display_asc';
$bt_nav->controller->displaySubPages = 'all';
$bt_nav->controller->displaySubPageLevels = 'all';
$bt_nav->render('view');
?>
]
