I am using the production address, I just copied and pasted the address from the shipping section of the settings in the store.shippingapi.dll
I have also doubled checked the user and am using priority shipping and the provider is USPS.
Every time I enable shipping I get the error mention earlier. If I disable shipping the order goes through perfectly, except no shipping costs are added.
So I would think the problem is with the shipping, at least that is what I think. Any other suggestions?
Thank you for your help.
