So i went to walmart and bought the legendary edition to destiny. It includes "Destiny", "Expansion 1", "Expansion 2", and "The taken king" Only problem is idk how to get it to work. I put in the disc that came with the packs and it didn't give me the option to download or install anything and when i try to play a mission i have for one of the included items it still says it's locked. What do i do? This is for Xbox 360.
