Hi! I've installed and configured your trial version of Dynamic Login 4.0.11
I've also configured Facebook integration and it works fine but only for the first login.
I've tried with more facebook users and every times I'm able to login succesful only for the first time. After the first login for each user already used almost one time I'm redirected to Facebook login and after go back on my web site I'm not authenticated.
I can login with Facebook connector for an already used Facebook account only if I remove the user by user admin control panel.

I've installed your module on Dotnetnuke 05.06.02 (144)

This problem is present if I select Facebook EmailAddress on User Creation Type of your module Facebook configuration
If I instead select 'Facebook UserID' all works fine all the time!

Please let me know if it is a bug or bad configuration.

Thanks!
