tried support - typed in my e mail address and doesn't work, and that is not the first time that has happened. I typed in my old email address and that worked, sadly i can't remember passwords to my old talktalk acc.
You have to use the same email address that you use for registering on here otherwise it won't work. The password will be one that you set up on gravatar, not your talktalk email password. have you no inkling?
i have bookmarked the talktalk web page and will see if i can work things from there. However i can't understand why my g mail is not always accepted, as i said it has happened before.
