If you have lost or forgotten your password, don't worry, it's very easy to fix. All you will need to do is go here and click the 'Forgot Password' link. That should bring you to a page to enter your email and then we will shoot you over a message to set up a new password to log in.
If you have tried the above step and had an error saying you do not have an account. That would mean that you did not create an account prior to ordering or after you ordered. That is very easy to fix as well, to create an account with any previous order history you will need to click here.
Make certain you use the same email address that you initially used for your order and it should sync correctly for you and have your points automatically added in.
