If you have previously created an account, there are two possible causes for this error:
1. The email you provided is incorrect.
a. Make sure your email is entered correctly (firstname.lastname@example.org).
b. If you have more than one email, try an alternative one.
c. If you initially connected with your Facebook or Google account and are now using an email login, the email associated with your Facebook or Google account may be different than the email you have entered.
2. Your password is incorrect.
a. Passwords are case sensitive. Make sure your “Caps Lock” on your keyboard is on/off.
b. If your password contains numbers, make sure the “Num Lock” on your keyboard is on.
c. Check your keyboard language setting and make sure it's set as the one you normally use.
If you forgot your password, click Forgot password? in the login pop-up window. The elves will send you an email with the next steps.
