Website works fine here, I haven't tested it under firefox 4 yet but in ie9 it loads up okay, did you click on the contact button up the top?
I have a screen capture of the site just in case you need it as the contact details are clearly visible here.
It looks interesting but it seems that it cannot be purchased/shipped to my location. They really need to drop the fancy pants website and drop the flash, I couldn't get the view cart button to do anything or get to a stage where I can work out payment details.
There should be some sort of ingredients listing available too instead of all the marketing fluff and lame media player.
EDIT: Hmm it seems visiting this url
