People seem to often put the incorrect username and password in the designated fields.
If your email address is firstname.lastname@example.org, your username is your full email address (email@example.com)
So please make sure that it doesn't just show "info" as the username, but the full email address.
All email accounts are in lower case, so make sure that you don't have any capital letters in the username.
Regarding the password, also ensure that the password is typed in correctly, that there are no spaces and that there are capital letters where needed if your password contains any capital letters.
If your email account password doesn't want to work please send an email from an alternative email account to firstname.lastname@example.org to verify your password.
