Epik header causes nav menu to be in in wrong place

Hi

I have uploaded a png logo 1125×120, this causes the nav menu to then be displayed below the logo.

Logo was actually ways smaller but I added a transparent bgd as couldnt see a way to add a partial sized logo via the theme header area.

Looking on the forums I then made this change to the CSS, reducing the widget area to 50% but then the menu titles end up too high up!

Please can you suggest how I can add a logo without altering the nav menu positioning?

Its a dev site, but I can send a screen shot if required

Thanks
