I have been trying now for at least a couple of weeks to convert a local profile on my Xbox, belonging to my daughter, into a child account under my main WLID and gamertag.
The end result of each attempt however has been the aforementioned error message from within the Xbox 360 dashboard.
'Xbox LIVE sign up is currently unavailable. Please try again later'
I must have created three or four throw-away WLID/email addresses for the purpose of associating with this gamertag but to no avail.
No matter what I do, at some point along the way, either after a) entering the WLID username/password account information or b) at the point where I'm entering in the credit card information associated with the adult/Xbox Live Gold account for validation purposes, it get this error messaging.
How in the hell then, do I create a 'child account'?
I didn't have this problem with one or two previous child account creations with already existing local profiles. Why all of the sudden am I having now?
In the end I just gave up and created another WLID (email) via the Hotmail account signup and then signed into Xbox.com, converting the auto-generated local profile into the same gamertag as I had assigned to the local profile I gave up on.
End result of this however, is that there appears to be no way to 'demote' this WLID to a child account managed under the aforementioned parent/adult WLID and gamertag.
WTF(unk) Xbox Live...? Again I ask the question, how then am I supposed to create a child account?
It would seem that it is only possible from within the Xbox Live dashboard and must be done from a local profile?
P.S. Needless to say, with regards to the original attempt (local profile), I really wanted to avoid this because my daughter wanted to keep her avatar which she had invested a fair bit of time in customizing, not to mention her gamerscore from the few games she is allowed to play.
