e newsletter not saving

Version 1.1.5 e newsletter

wp 3.2.1

Hello, when I try to change a password in e newsletter>settings>outgoing email the new password does not save. How do I fix? The old password was 7 letters, the new one is 11 letters long. Each time I save the asterix’s still show as 7. I tried deleting the password entirely but the old one seems to be stuck.
