In 2010 I had a Zune Pass for my Zune HD. Since getting a Suface Pro, I've re-subscribed to XBox music pass and it still links to my previous setup. However, out of the 4 original devices I had registered, 2 computers have the same name as in 2010 but different OS version and 1 laptop no longer exists. Together with my Surface Pro, I've quickly depleted the # devices I can add/remove in 30 days. I searched for customer support # or other means of contact but kept looping back to the forums.
