When I try to download an App it tells me, "Your account is not valid for use in the U.S. store. You must switch to the Canadian store before purchasing". How did I ever get into the American Store? was it when Idownloaded the US Open App last week? How do I get back to the Canadian store? Hope someone can help me.
In the bottom, right-hand corner of iTunes there's a flag in a circle where you can switch between stores according to country.
