Ok. I've posted on here two times already, and this will be my third for this problem. Everytime I try to buy silver on 360 it says "Silver sync failed" on the game and on the dashboard, it says "The application is unavailable". Seriously? I've contacted Microsoft, they said that Bungie should be notified about this, and that Microsoft themselves could not help me. But so far, Bungie contacted me once on my forum post about this. I responded a couple times, hoping for a solution. Essentially, they said to clear my hard drive's cache and then they stopped responding after that! They did say one other thing but it was essentially them thinking I was actually able to make a silver purchase, but that was the FREE silver I got from the update itself. So please Bungie, if you can take time out of your busy day to actually help, that would be great.
