There could be several reasons.
1. Most of the time is that you have entered the email address or password incorrectly.
2. If you signed in with Facebook or Gmail the first time, you will need to click the "Sign in with Facebook" or "Sign in with Gmail"button to log in.
3. If you still can't log in, please click this link to reset your password. We'll then email you a link directly to your registered email address to reset your password.
We recommend checking your junk and spam folder if you're having trouble finding it.
