FedEx default payment plugin not working

-- url of the page with the problem -- : www.paperrollexpress.com
-- HikaShop version -- : 2.3 Essential
-- Joomla version -- : 3.3 Stable
-- PHP version -- :5.4.26
-- Browser(s) name and version -- : Chrome 35.0.1916.114 m

I've looked through all the documentation, read all the forum entries, entered dimensions and weight into a product, turned on the FedEx plugin and it still doesn't show up!
