We are aware that the recently released Crackdown DLC is causing some gamers to experience a reset of their saved games when they engage in co-op play. The team is working extremely hard to identify the issue and has provided steps to avoid the problem.
Simply follow these instructions:
1. Sign-in to Xbox Live
2. Start Crackdown and receive new Title Update (if you haven't already)
3. Begin a Single Player Campaign game
4. Once loaded, press Start and choose Quit
5. Reboot Crackdown (soft reboot or hard reboot of console)
By following the steps above, this will ensure that your Crackdown experience will be trouble-free. You will then be able to enjoy the new title update features, the Free-For-All DLC pack, as well as all the goodies found in the Getting' Busy Bonus Pack.

A permanent solution will be released with the game's next Title Update, which will be available in the very near future. NOTE: Unfortunately these steps will not restore an old saved file. There is no workaround for this. If this changes, we will post additional information in these forums in the future. We sympathize with those who may have lost their saved files. This was an unforeseen incident and the team has worked diligently to find a solution in the shortest amount of time possible.http://forums.crackdownoncrime.com/f...ead/29363.aspx
