This is offtopic, but since I’m in a good mood with the weekend coming up I’ll answer you anyway 😉
The problem is there because the menu you have chosen to use on the page is meant for links that scroll down on the same page. Therefore a piece of javascript is included by the theme that disables normal link behaviour in favour of scrolling. But since the link is not to another place on the page the javascript can’t scroll anywhere and nothing happens.
As far as I can see Videotouch has a whole bunch of possible menus. Just try one that is meant for external links.
