UPS Shipping Method Version – Woo Commerce

Hello i was using WooCommerce UPS Version 1.0.8, it was working well, populating shipping costs but it wasn’t allowing me to use negotiated UPS pricing for my client. So i downloaded and licensed UPS Shipping Method Version 2.0.4 – using all the same UPS information (account,access key , etc) it will not show any information – woocommerce does not even recognize the UPS shipping method on the checkout page.( I get the Sorry, it seems that there are no available shipping methods for your state) If i enable another method( i.e. pickup) it will use that, if i reactivate version 1.0.8 that version still works. Any suggestions are greatly appreciated. Thanks
