Microsoft account live problems, email doesn’t exist

I have been trying desperately to give parental approval to my daughters Xbox email account, using my own already existing accont.live microsift email and despite several attempts to approve this via, account.live it repeatedly told me name and birthdate were missing, yet, these were fully filled in on my microsoft and xbox live / email account, and, I could not gain access to my daughters email as I kept getting the screen "sign in as an adult" and so the loop repeats. 

As I have a fully filled in profile for my email, I tried the delete it all and start again thing! So, that was I now know the most wrong thing I could do!

Now, I cannot use my microsoft account on account.live it tells me the email address doesn't exist now and won't accept it, so every bit of my data life and pending downloads are all held in cyberspace. I cannot access my windows phone settings and cannot access Xbox live, in other words one small issue that has lasted now since November 2013, has trashed my entire cyberlife!

Is there hope for an eejit like me???? I throw myself at the mercy of the board :-)

Best regards

Derek
