Invalid Access code

Once you have successfully used an access code (i.e logged in successfully) it becomes invalid and cannot be used again. Access codes also expire after 3 hours and therefore will also come up as invalid if used after the 3 hour mark.

You will need to request a new access code in these cases. This can be done easily by re entering your email address at, this will trigger a new access code to be emailed to you, or you can use the "Need help?" option from the access code entry page.

Sometimes mail gets caught in the spam folder. Check it to see if your access-code made its way there. Note that some email service providers call this the "junk folder". To help prevent our emails from ending up in your spam folder you can add [email protected] and [email protected] to your contacts.

Full inbox

This one is rare but it can happen. If your email inbox is full, new mail will be rejected. Make sure it has enough room for new mail to come through. If your inbox was full, you can have your access-code resent.


Usually email takes up to a few minutes to arrive. Sometimes, however, it may take several days. Other times it may fail and nobody is informed. If you find yourself in such a situation, it could help to have the email resent.
