its not just you. I am unable to access the marketplace website. I can get to the landing page but every other page takes me to a "not found" page. After 3 lumias and now a purple tint on my newest on, I get home to find that zune no longer allows me to access the app marketplace. Fine, I go online and type marketplace.windowsphone.com (which has worked since it was launched last year and... not found).
