To expand on this, log into the SE Account Management system and click the Account Information button. After the confirmation dialogue, you should see details about your account. You will have a field for Country and Regions--your Region needs to say "The Americas".

You may also want to open your config file as well to see if it has a region code of zero (can right-click it and open with notepad).
