@ kostas-evan
I’ve checked your account and have verified that it has indeed been closed. I would really like to help you with your concern but Windows Live Customer Support team is tasked to determine whether an account has been closed for a Terms of Use violation or has been closed incorrectly.
For instructions on how to get in touch with Windows Live Customer Support, please check out MSFT Roopa S’ Solution post “Error on login: Account Closed Access Denied”. To view the Solution post, please access the link below.

I should remind you, however, that Windows Live Customer Support is currently on backlog and that they may be unable to respond to you in a timely manner.
