Shipping not working

Hello, I have recently updated to Jigoshop eCommerce Version 2.0.8. Everything seems to be working just fine, except for my shipping. I have purchased a few extensions from you (table shipping/premium shipping) but none are working properly. I have emailed directly but no one has responded. Can someone please help? My shipping rates need to be as follows:

US Shipping: $5 per item
Foreign Shipping: $15 for first item, $2 each after that

How do I achieve this configuration? It seems that it just keeps defaulting to only US Shipping and not allowing to change any countries or state in my billing address to pull the Foreign Shipping rates. I believe it has something to do with the dropdown fields to country and state not working…
