Bungie please help!I have tried to download rose of iron only to see this item is not available. I have tired the uninstall, reinstall trick and it hasn't workded! It still says product is not available!! I pre ordered at GameStop (not doing that again) and it is not working. I entered the code and it says product is not available! Is this a Bungie issue? Or a Microsoft issue? Please tell me if it is and when it will be fixed!!! First download tried on 9/19.
