MarketPress USPS No valid shipping options found. Please check your address carefully.

Ok, so I know you have seen this before because I have been reading past tickets but haven't found my solution.

I am using MarketPress (gridmarket & grindmarket) using USPS calculator, have filled out all shipping options*, have put received and put in API username*, have checked for extra spaces before and after*, have contacted the USPS division that handles the API and received verification via email that the account is on the Production Server*(attached). But im still getting: "No valid shipping options found. Please check your address carefully."
