Question about Outlook Express

I editted my DOB and created the "child requiring parent permission" issue with my existing account.  I created a new account so I could give myself permission and verify that I am an adult by making the .50$ credit card charge but .....even though on the new account I have chosen Canada as the region, entered a Canadian phone number, entered a Canadian address, chosen Canada as my work region ....  the credit card form to be filled out to prove I am an adult defaults to the US with no drop down to change this and so I can not enter my billing address since the Canadian postal code format is different and Ontario is obviously not in the drop down list of states.
