First, determine which error message you are seeing:
"Email or screen name provided was not found."
In this case double check the spelling on your screen name, or try entering your email address instead (either should work). If this account was created through the app, make sure you are using the same email address as you used to register there.
Note: If you crowdfunded Hydrow through Indiegogo or pre-ordered on our website, you will still need to create a new account the first time you log in. No account is created for you automatically when you purchase. If you were previously a beta tester, however, you should be able to log in and use the same account to keep your progress.
"Password provided is not correct"
Check that your password is being entered correctly using the "Show" button. If you are still having trouble you can also try the process in this article to reset your password.
Something else?
If you are receiving a different error message than either of the above, or a different symptom entirely, please Contact Hydrow Customer Care. Make sure to describe the problem and , if possible, attach a picture of the error on the screen to help us better understand the nature of your issue.
