Ah, it's a Template Monster template. They've put in a bunch of nested DIVs, one of which is holding your nav menu off to the right. You can work out how to deal with it -- maybe -- using Firebug in Firefox.

You should know that trying to customize TM templates to any extent will be difficult, and our ability here at the forum to help will be reduced, due to their non-ZC-standard code. You might try asking TM for help.
