Is anyone else having trouble connecting to the iTunes store?

My connection to the store is good. US Store.

Last night I couldn't sync any songs or applications that I have purchased. I just get an error that my machine is not authorized. All the applications that I purchased were then removed from my iPhone. My wife is having the same problem with her iPhone. We lost all our applications. They are in iTunes, but when you double click them, the iTunes store authorization pane pops up. I entered my name and password and I just get an error message about permissions are wrong and to fix it. I then tried my wife's account again. I went into iTunes, downloaded the free song of the week and tried to play it. The permission box pops up again. Log in, and get I still get the error message message. I then got a message saying that there is a problem with iTunes and that I should reinstall. So I don't know if iTunes is hosed up or if it is the iTunes store itself. I'll try again tonight and see what happens.

Something must have broken when I moved my Home Directory to another drive. I reinstalled iTunes and all is OK now.
