JFBConnect Error messages with Kunena on new user registration

After installing Kunena my jbfconnect facebook registration no longer works. Or, more to the point, it creates an account, sends an email with the account info & links to FB, but redirects to an error page with the following warnings:

This only happens on new user registration. After you refresh the site and login using either the login module or JFBConnect, it works fine. Any ideas how to fix this so folks don't get the error messages? Thanks!

Okay, thanks for the help. At least I wasn't doing something drastically wrong. I'll keep an eye out for the K2.0 profile plugin. Thanks for the fast response.
