Error Message " Account Not In This Store"

Hi all,

I had reviewed many post related to this error message, all of the solution guide the user to change to the proper store (US store) log off from the store account an login again.

Tried all of those solutions with no success, I still get the message "Your account is not valid for use in the Canadian store. You must switch to the U.S. store before purchasing".

Never used the Canadian store, I use a US credit card with updated delivery address within the US.

What should I do next???
