DLC maps not working

[justice_in_a_can]

I'm using the MW3 dedicated servers and everything goes fine until I try to play any of the DLC maps (except Terminal, that one works fine), when I choose one of them and click start game nothing happens, nothing loads or anything
I tried checking that part of the documentation about installing the DLCs but it doesn't appear anywhere, pls help

To play DLCs you must install them. We don't provide any game files

Ok, I have the DLC files, where do I put them?

Since you have to ask where you have to put them its clear you pirated them, which we can't support.
