2- Wordpress CSS / Dropdown Edit

I have installed a WP plugin to accomodate a 2nd tier dropdown in the main Page nav bar for Solar & Wind Products Page Button. My theme is Revolution City. The dropdown seems to be working OK but the installation is affecting the CSS of the body of the site it seems, really only for the Solar & Wind Products > Water Heating & Pumping > Solar Hot Water Page. However, the main nav bar is notably messed up visually. I need the buttons to look like the background bar texture. We can turn off the plugin I think to see what it should look like, but need to see the extra 2nd tier. At this point i think all we have to do is play with the CSS.
