Wordpress - MooTools sub-menu not working correctly

I have installed the Akiraka theme from RocketTheme and am trying to get my sub-menu's working. Currently when I hover over the main menu item a w开发者_C百科hite box displays where the sub-menu items should be.

The site is: http://testing.bfcmv.org/

I have compared everything to their site and can't see any difference between my configuration and their configuration.

Which browser/OS are you using? It looks to be working OK for me.

Tested on Linux Firefox/Chrome

I was trying to use the most recent version of WordPress 3.2.x and found that I should have been using a 2.x version.
