When ever I try to play the campaign my game closes and takes me back to the dashboard. It would finish loading the mission then just quit before the level started. The first time this happened I was playing the mission Behind Enemy Lines and got killed by a wraith while listening to a data pad, then it crashed. I have no idea if it is related to my game crashing but I figured I should mention it. Also as far as I know now this only happens in single-player I have not yet tried co-op. I am wondering if this has happened to anyone else, or if anyone knows how to fix it.
*it works fine now, not sure what happened but after a few weeks it just started working again.
