I have two 360's and just started playing this game again on my newer HDMI box. Anyway, all my achievements are intact but my profile is completely blank - I have to start all over again. I thought the game saves traveled with my memory stick??? I had finally gotten all 500 green orbs and was around 11 shy of the white orbs ... now back to orb one ... GRRR!!!
shareGo into your memory options on the original system and copy your game info to a MMU, then plug the card into your new system and copy it onto the new hard drive.
shareYou have connected to Xbox LIVE to ensure you are playing on the latest update? Sometime that can stop you accessing your stuff in a game (since you may be using an earlier version of an update). I believe Crackdown should have an update upon connecting to Xbox LIVE.
