Sorry about your My Virgin Media access issues, though I'm sure we can help
I'd like to know what error is returned when the 'forgotten password' link fails for you, would you mind posting a copy of it on here please?
It would also be a good idea to try accessing via a different browser.
Other than that, if there is an issue with either the email address or password used then we'd need to investigate further. Please reply to my PM (purple envelope icon, top right of page) with the requested information and I'll see what I can do for you
