Using the 'products' theme, I have no navigation menu

Hi, I have installed this theme ‘product’ as it is one of the recommended ones for using with you QA plugin. I am setting up at support.assistcomputing.co.uk

As you will see, I have no navigation menu (below log before content) showing on the page, it shows nag in the previews on your site for that plugin and I don’t understand where it is – I’ve trawled the setting/options. Please help.
