Its late and were bored.

hey to save you guys some trouble with the new map pack i had to go to the forums to locate an answer to the crash problem. Basically you need to go to your library, click on call of duty modernwarfare 2, then right click and go to the downloadable content, click updates, scroll down the drop down to do not update and uncheck the box, after close the window and repreat the steps except this time you reactivate everything and close again. This will allow the game to download the second patch that was sent with the maps, for someodd reason IW decided not to make it one patch and split it in two, so some can play and some cant. But this fixed the problem for me, ill catch you guys on later.
