Chris,
The JFBCFan module was actually discontinued. We had too many stand-alone modules that were too confusing to configure and setup as well as keep up to date.
Instead, we now have the SCSocialWidget module. With that, you can configure any social widget from any of the social networks we support. For the Fan module, you need to setup the SCSocialWidget with a Facebook -> Like Box widget. Then, configure the settings in there and you should be good to go.
I hope that helps explain, but should you need more help or have any questions, just let me know!
Thanks,
Alex
