For some reason I only get a freeze up when I start to play the 'Campaign' and this has only occured during Mission 11,I'm on the grass runway,get the engine started up,always using CEM and before I can get airborne 'FREEZE'.
I then have to get it back to Windows before I can close COD down properly,

it's very annoying and I don't get this with any other game,again maybe the next patch will sort this.
