Restored network-configuration - xbox live-friends lost

Greetings adad03!

[quote user="adad03"]I've just restored my xboxconfiguration to factorysettings which solved my problems with connecting to xbox-live.[/quote]If this refer to the process when, or if, you restore your console's network settings back to factory defaults, it
wouldn't affect anything related to your profile savings. I think it's more of an issue with contents being corrupted.

Follow the steps up front and let us know how that goes and we'll work from there.
