Move navigation to the right in the header

Hi. My site is at http://uscostnew.virtual.vps-host.net

The theme I am using, Jupiter, has 2 header options: Classical navigation, which is logo above menu, and modern navigation, which is logo beside menu (what I have active now). I need to know how to move the menu to the right, or change the logo div or something, because right now the menu doesn’t work properly and the logo or its container seems to be overlapping the menu so that it can not function.

Any tips are appreciated. Thanks!
