I fired up the Xbox today and my on-line profile has disappeared. It cannot be deleted; it simply isn't there. I checked my game save data which seems uaffected other than it says that it belongs to a corrupted profile. Not surprising since my profile doesn't exist on the hard drive. I am using a wired connection through Cableone. After receiving the message that profiles cannot be downloaded followed by the number 80070571 I tried it on my other box and it worked fine.
Question: I own three Xbox live profiles, two for my sons and my own. Why can I access the profile from one console but not the other when they are connected to the same modem via a 4-port switch?
Concern: Is this a hack like the one PSN experienced a while back? If I recall it took Sony a few days to let everyone know that they had been hacked and lost subscriber's sensitive info. Can't honestly say I would expect anything different from Microsoft.
