Header Drop Down Navigation (Where to insert the code)

Hello and thank you for such an excellent theme. Atahualpa 3 is superb!

I'm trying to insert a drop down style menu called "PixoPoint Multi-level Navigation Plugin". The docs state to insert "<?php if (function_exists('pixopoint_menu')) {pixopoint_menu();} ?>" within the header. However everywhere I put it, I never get a result that's acceptable. I want it below the search box across the entire header.

So the question is. Where in the header.php file to I insert
<?php if (function_exists('pixopoint_menu')) {pixopoint_menu();} ?>

?

Thank you in advance for your help....
