Email address on my account so its sending an email to nothing.
I now cannot log into my account to activate my email address.
No, you can no longer modify your profile, for that you would need to access your account and to access your account, you need the confirmation code which was sent in outer space. You accidently got in a vicious circle. Anyway, without the confirmation code, your account will never be activated and get online.
