I'm not sure why you'd be seeing any of the problems you mention above. There's were a few issues with earlier versions of JFBConnect that concerned the channel feature and there have been substantial changes to the Facebook API over the last year which could cause the redirect loops you're seeing if you're not on the latest version. Can you please tell us what version of JFBConnect you're using? The latest release is v6.3.0.
Also, please post from the account you subscribed to JFBConnect from. Priority support is for active subscribers only.
Thanks,
