I had the same problem with IE11.

Your site url defaults to http://www.wolfeinteractive.com but the fonts are being requested from wolfeinteractive.com
via F12 console in IE11:
src: url(‘http://wolfeinteractive.com/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/assets/fonts/entypo-fontello.eot?v=2’);

I adjusted my site url to get it to work in IE11.
