I tried the “Forgot Password?” link, but it didn’t work!
It could be that the email you registered with is different than the one you have on file. Try logging in to the app with the original email. Once you have logged into the app then you can go to the settings tab and change the email you log in with.
Alternatively, you can use the link on the log in screen for New User Registration and re-register your account. This will create a new login and password.
