Trying this again as I didn't realize it was region restricted before. Trying again and hope the key works this time and restricting it to NA so I don't get another surprise.

Please don't feel obligated to say 'thanks' just for entering the GA, although a simple 'thank you' if you win would be nice. I respond to all comments up to a point close to the GA ending, so don't comment if you don't want replies.
