Cant even launch game.
Hey there,
For Call of Duty: Modern Warfare, Blizzard Technical Support is only able to offer support for install, patch, Blizzard account, and purchases made through the Blizzard store.
We cannot assist with launching the game nor crashing issues within the game as we do not have information on the game servers. For this issue, please contact Activision Support or refer to the Modern Warfare forums .
