big space between content and primary menu

Hi, I want to rebuild our website. I do this on www.hagmeijer.nl Now I am trying for hours to reduce the big gap between the content and the primary menu. Nothing and nothing results in a good solution. I searched at the internet, I searched in the Catchthemes forum, but I cannot find any solution. Hagmeijer.nl is a fresh page without any additional css. Please help. Regards Hans Hagmeijer
