Theme crashing

Hi there!
I've installed studiofolio theme and it's not working correctly:
- First, I wanted a homepage like your demo home - fullscreen (http://demo.undsgn.com/themeselector/?theme=studiofolio) and I couldn't get the image fit to the bottom browser, and appears a blank space between the image and the footer. I've tried with demo content, reinstalling the theme several times, and it's impossible! Nothing works!
- On theme options, the home-page category name has changed. It's weird! I've reinstalled the theme again and I see the copy correctly.
- I can't upload revslider examples.
- Text added in a slider layer is not responsive.
- Arrows images on slider and back to top doesn't appear.
