Master Slider Full Width not working

Hi,

I love this slider and I installed it to my Lighthouse – One Page Responsive WordPress Theme .

However it seems that it doesn’t scale to full screen no matter what I do. The site I am working on is on my local machine so I cannot show you a preview unfortunately. Is there something ridiculously simple I am missing here?
