Restoring profile information

Unless you wrote down what was in your bio etc. then you would have to try a remember i'm afraid.

No one here can tell you what was in your bio.

Your game saves would be saved on your hard drive. If you go to your settings and storage, you can find the games you want to remove the saves from and delete those save files (they are saved separate from the actual game files). Game saves on the 360 are
not automatically saved to the cloud unless you have them set up to be saved there. If that is the case, you can also access your cloud storage and delete those save files. You don't have to delete your profile and redownload it.

However, depending on the game, some information may be saved on the game's servers. In those cases, you would have to start over on another profile.

IloMilo and BattleBlock don't use local gamesaves or I wouldn't have this issue, I could try playing offline, but somehow I don't think they are server based saving. Looking online I believe they are saved as GPD files in my profile, but thinking that way,
these are likely the same files that store achievements, which I seem to recall are also pulled back on restore

These, like many arcade games, store the game save data as part of the game download file. You should be able to delete the game from your storage device and download it again, allowing you to create a new game save.

Try to delete your profile from the xbox , not profile and items just profile. Re-download your profile. If your information is restored good if not call Xbox Live Troubleshooting 18004699269
