I am using the map manager and downloaded the ugx christmas map among a few others and none of them show up when i click on mods in-game. I have tried using the console to enter the maps and that doesn't seem to work either. I have the maps in the mods folder of waw and the manager detects them but I can't find a way to load them. I don't see what else I could do at this point, and this is too frustrating to keep trying to work out.

your pc name \AppData\Local\Activision\CoDWaW\mods
is where they need to go
