All you have to do is download this:
https://66.7.221.247/~textureh/DLC.rar and just copy it into your Black Ops folder which is usually located in Drive:\Program (Files)\Steam\SteamApps\common\call of duty black ops.
The file is too big to be uploaded to MPGH so...
Thanks to @rowan112 and @House for uploading.
Enjoy :]
