Right I've changed your password and successfully logged in as you on my pc using Internet Explorer to test.
I know this may sound a little tedious, but I'll need you to delete your cookies & close, re-open your browser once more before you log-in using the new password. Once(if) you're in, please change your password to something suitable.
I'll email your password to you now.
PS, if you change your email address you will require an admin to re-activate the account for you, so some forewarning is recommended.
