Our suggestion would be to upgrade to at least 3.2. It's been out for over a month now, and likely fixes whatever issue you're experiencing. For the full changelog from 3.1.0 (from early January) to 3.2.1, available now, see:
www.sourcecoast.com/extensions/jfbconnect/changelog
Either way, again, please post from the account you subscribed from. I'm pretty sure I know what the issue likely is, but again, support is for subscribers only. If you don't have an active subscription, please see:

Thanks,
Alex
