HELP SHIPPING ERROE

[casey2210]

When I try to check out of my own store I get a shipping error that reads 

"This Address is not supported, please select another."

I have tried everything I can thing of 

here is the link to my store

Aside from actually checking out it seems to have accepted my address that I entered. Are you getting this error prior to the card details being entered?
