Hi
After checking out this forum I followed the advice given to click on the forgotten username link to get a reminder of the username of the primary account.
It offered me two usernames but I knew about both and as expected both of them are listed as secondary account holders.
It seemed to work for the original poster on the issue but this did not help me in any way.
This prevents me from adjusting the settings within my account
please help as this is as far as I can get with self help
thanks
Paul
