Missing Dr Pepper Promotional Camo on Xbox 360

With the announcement of Battlefield 3 being backwards compatible, I decided to hop on the game again and have some fun. I went through the customization menu only to find that I'm missing my Dr Pepper promotional camo from the launch of the game. I have some of the dog tags as I was never able to gather enough codes for the tags before it expired. I was wondering if others are experiencing the same issue and know of any fixes?
