I noticed that Getaway map bugs the game. I was playing on a server then suddenly the map changes to Getaway. It shows the Dark Green and Red Boxes while the map is loading and my screen goes blank (I'm playing on windowed mode). I have to hold the power button in order to restart my Laptop. I tried to re-download MW3 directly from Steam (Yes i bought the game on Steam) and re-download the DLC provided by you guys. Still I have the same problem. Maybe the map itself is glitchy?

It has been working for me. Are you sure you put the DLC in the right folders? The .ff files go in the /zone/dlc folder.
