Illustratr theme: hover and column width issues

Hi there, just need some help getting my portfolio site using the Illustratr theme all set up.

1. The red box that’s supposed to appear when hovering over portfolio photo doesn’t happen. I’ve reinstalled the theme to no avail? Ideas?

2. When I use shortcode to display 3 columns on my portfolio page, my content area of those columns is only 800px, whereas on the Live Example site, the 3 column layout is 1100px wide. What am I doing wrong here?

Thank you!

The site I need help with is http://www.mforbush.com.
