Here's a list of common issues that may prevent you from logging in:
You have created a password but have not received the email that contains the link
to activate your password. In this case, please check your spam folder.
You have not checked to see if you have received the email to activate your
password and/or you have not clicked on the activation link contained in the email.
The username and password fields have been pre-populated by your browser but
when you try and login, the system displays 'Invalid username / password. Please
retry.' To resolve, please delete what has been pre-populated and re-type your
username (this will be your email address) and password.
