When I click on the "purchased" tab in the app store, it's just sitting their all by itself with a button that says "DOWNLOAD". I click it, I get the spinning cycle it's doing something, and then it just stops. I've tried restarting and it doesn't change anything. I just deleted Mavericks from my "Purchased" section, and no when I try to download it from the App Store, it doesn't even make it's way over to the "purchased" tab. I'm running Snow Leopard with the most recent update and I have 11GB's of free space. Anyone know what it could be?
