Font Awesome 4 Menus not working

Hi,

I installed the Font Awesome 4 Menus on WP 3.9.2 running CouponPress responsive. I’m unable to get the icons showing on the menu, I used the CSS Classes when adding the icon value but nothing is showing on the menu.

I checked the Don’t load Font Awesome 4’s stylesheet (use this if you load Font Awesome 4 elsewhere on your site) but still not getting the icons to show up.

Is there anyway to make it working? Did you have this issue?

Thanks
