I'd like to change the email address on my account, however when I go to do this it says the email address I want to change it to is currently in use.

I went to the "Forgot Password" link and sent a password reminder to that address - it emailed me a link which I clicked on and it gave me a new password. But I cannot log in with this password (it just takes me straight back to the login screen, with no message).

Any ideas?

Andrew.
