Forum:Call of Duty: Black Ops DLC

Yeah, so I went to Gamestop today to pick up a newer copy of Battlefield 3 and decided to buy Black Ops one while I was there. I bought it again because I liked the Zombies mode better than all the other CoD Z modes. But when I went to the marketplace to re-download the DLC's I had purchased, I saw that none of them were there. And when I tried to download the DLC's through the game a message came up saying "Not available for download." So I'm wondering if they removed the DLC's all together.
