My logo is blocking parts of my menu

Although I have tried several approaches in Appearance>Header, I have been unable to get my header right. I selected the option of placing my logo above the menu navigation line, but it stubbornly appears to the left. As the included photo shows, not only is my logo placed to the left of the menu line, it overlays the left most items of the menu including the home link.
I am using the Ultima theme and my domain is: Any help you can give me would be greatly appreciated.
