Recently when I try to download app updates, a dialogue box opens saying that my account is not valid for the US store and I should switch to the Canadian store, so I have been unable to update several apps once I have been notified that an update for one of my apps is available. All of my apps have been downloaded from the usual App Store. I believe I had this happen once before and whatever the problem was suddenly disappeared, but has now come back. Has anyone any suggestions as to how I can go about fixing this problem? Thanks in advance, Wolfe10
