In your other post you mentioned that you just upgraded or switched to Joomla 3. If it's a new site, it's possible you haven't set your subscription ID. Go to the Basic Info tab in Autotune, scroll all the way to the bottom and make sure the 'SourceCoast Subscriber ID' is set.
Then go to the Facebook App tab in Autotune and hit the JFBConnect toolbar 'Refresh' button to re-fetch your subscription status from SourceCoast.
Let me know if you continue having problems after trying these suggestions.
Thanks,
