Woocommerce checkout page breaking id=”main_in”

Hi,

I realy like the theme and it works almost perfect, the only problem with it is with woocommerce.
Somehow in the checkout page it breaks the theme id=”main_in” div
and seperates the everythingg from the id=”right_wrapper” div

I searched for hours and can not find a solution. Woocommerce says its a theme problem and dont want to help.

Any help would be verry nice.
