If you have reset your password and are sure you’ve got it right, then it probably isn’t a password problem, it may be a username problem. Most often, people attempt to log in with their full email address as the username. However, your username is only the beginning portion of your email address, (everything before the @ symbol). So if the email address you used is email@example.com, your username is photo123. 🙂
If this doesn’t seem to help and you still are not able to access your account, please send me an email at firstname.lastname@example.org and I will be happy to get you all squared away!
