Just as the title says.
I tried on my console and I tried on the website, but on the console it tells me that I'm not connected to the internet (which it is connected) or my storage device is not in properly (which it is) and the website tells me I have found a glitch. All this came about when I downloaded The Giant in WWE 2K14 in the WWE Shop. Even in the game it tells me (after I downloaded him) that the "Downloadable Content List failed to load" each time I try to access it. I've already contacted 2K about the in-game problem, but the Download History is on Microsoft's head.
