I have the same problem. Joined back in May and i still can't login to Myvirginmedia portal. Tried the credentials i used at the time of setup but not working. Tried resetting password but not joy. Tried forgotten username and doesn't recognise my login name. Tried to re-register for Myvirginmedia and it gets to the page where is select my username, password and security question and it gets to a page where i select the Child and Web Safe settings and then it bombs out with an error.
