Have any other Mac users tried to purchase anything from the store today??? I even--at Sydd's email recommendation-- went and downloaded the newest version of IE (5.2.2 for Macs), but I still get a "data encryption failure" everytime I try to checkout. (And, oddly, the buttons at the bottom of the page are broken, too--I click on the ones at the lower right, which I think are the correct ones. The ones on the left take me back to my personal info.) If anyone's still monitoring this thread, could you check with someone knowledgeable about Macs and see if they can tell us what is going wrong?
