I have just upgraded my Xbox live account to the Family pack! I have added one member but Xbox keeps asking for my details to log into live to a add a second? Windows live seems to loop at this point and does not recognise me ! However I can sign into live on my pc but strangely when I sign into xbox live on the pc it does exactly the same thing! Answers please would be appreciated if you can do this a.s.a.p due to the fact its my oldest son that I am unable to add!!!!!!
