Does FreeStyle Dash let you download it? You can also find TU's for OPS 2 here: http://www.xbuc.net/browse/?search=black%20ops&page=8&page=1
But I can't find yours in it. But there are other TU16s for other Pal versions of the game. Why don't you just get a different version of your game? Like a different Pal version or an NTSC-U. Because there is no difference at all in what type of game you have, they are all the same. And its always good to update, I hate people who don't update, makes no sense.
