I've owned MW3 for a little while now and just downloaded the Collections 2 DLC today. To my dismay when when starting up a game, it simply states while searching that there are no games found, eventually timing out. I have to disable DLC to get the standard maps to work again. Why is this the case? Does no one play the new maps or is it simply an issue with matchmaking/ servers with the DLC?

I'm playing from Australia, so it could be some region issues also. If i can't get a resolution, then I'm gonna push for a refund on the DLC because I dont want to spend money on something that doesnt work or no one else actually plays.

An answer would be greatly appreciated.
