Issues with Nictitate theme update as well as header and footer

Hi,
I need help with this and I am not sure if anyone can provide it. The people through Kopa Themes will not respond to me about how to update my Nictitate theme. Any help would be much appreciated.

As far as the header, I would like to have the header go up with the page as you scroll down rather than stay in view.

As far as the footer, the navigation bar on bottom is on two lines for some reason. It wasn't always that way and I'm not sure what happened.

The site is

Thank you so much.
