Help! my checkout form has gone loco! T_T

in the checkout page, “Your billing/contact details” section, the first name, last name, address, city, country, postal, phone, email went to the right and i need to to put it right back in the left. all i did was update the wp e-commerce plugin. i’ve tried rolling back to the previous version but nothing happens.

here’s the link
“checkout a product first to go the the checkout page”

any help would be appreciated! ^_^
