[SOLVED] menu styling location - firebug

Perhaps I've been staring at this for way too long, but need some direction.
I am "fixing" a theme that was edited withOUT using the HTML/CSS inserts. I've got nearly all of it squared except the pesky background of the menu.
When I view it through firebug, I can't seem to locate where the previous person made that change. the menu div literally comes up empty. but if I go into "css mode", I can see the background image file being called up. I have added that to html/css inserts and swapped over to the new theme, but nothing changes. (i don't suppose it's as silly as needing that "!important" in there??)

This is the code I find in there (and that I added to html/css inserts):
here's the site (a page w/out any sliders/don't use the home page): http://www.gordisfishandsteak.com/about/

I tweak the menu features inside of ATA and nothing changes (meaning, I can't even "break" it on purpose)....
