Main slider does not appear on Freak Pro

Hi everybody:

I have recently upgraded from the Freak Theme to the Freak Pro and the main slider does not work at all. I have check that all the options are OK, enabling the main slider on the HomePage and creating three slides in order to prove if it really works….but nothing, the main slider does not appear. Has this anything to do with the page layout? For the HomePage I am using the Portfolio Default Page.

I do not know where the problem is. This is my website, if you can check it out:
