Hi recently I have completed the game ‘Batman: Arkham City’ so I am very excited about this game this is the good game I have seen, but there I have not find any of the achievement there in this game. And also I have completed the story mode for the side missions in Arkham City. So after that I have close the game and the next time when I try to play the same story mode again to complete the remaining part of that, the message pop up for ‘Damaged Downloadable Content’ and then I automatically switch to the X-Box Dashboard. So what is this issue all about and why such thing happens there for this game, this is the issue or the Glitch there in this game or I am noob to do this thing, so if you guys have any of the suggestion or any of the ideas for this issue then please let me know about this, any of the reply will be appreciated. Anybody have any clues how to fix this?
