Starting at the end of last week, when I click on my Shopping Cart for the iTMS, it acts like it is connecting then, it just stops and I have the white screen that says iTunes Music Store where my shopping cart should be. Recently I was getting the popular 502? error, now it just doesn't load. I have tried my home computer (connected to the net via DSL) and at work on my computer and get the same thing. Anyone else seen this or know how to rememdy it?
