[Plugin: Constant Contact API] Widget settings not saving. Stuck with default.

I just upgrade my Constant Contact API plugin to v2.1 and now I go to my widget settings and I set it so it doesn’t include the first and last name so I just have the email, click save and then….the changes don’t take effect. I go back to the settings and they’re all back to their defaults as if I had done nothing. What’s going on here? Is there a way I can go into PHPmyAdmin and make the changes there?
