Hi all, I've been looking forward to upgrading to Max OS X Lion to take advantage of the new features. Unfortunately, for some reason my Mac App Store does not seem to work. Whenever I try to buy something, the Buy button simply takes me back to the product description. I've tried reinstalling the App Store app, but to no avail. So I thought I could perhaps buy a disc version of OS X Lion, but apparently it was never released on disc. Does anyone know if this is true? Or how I can fix my App Store so I can download it? Thanks for any help!
