Shiprush not getting negotiated rates

Hi, I'm new to shiprush but read the guide to getting negotiated rates set up located at: http://www.shiprush.com/product_docu...First_Page.htm . Unfortunately after getting in touch with UPS about configuring the account it seems that shiprush is not pulling down the same rates we get when we enter package data in to worldship. Is there something else I could be missing? It seems fairly straight forward.

Thanks!
