In Joomla, the name of the module is 'SCSocial Stream'. If you cannot create a new instance of the module, please use the Extension Manager to see if it is properly installed. If not, you can reinstall the module from the JFBConnect package. If you unzip, the file will be located in /packages/modules/mod_scsocialstream.zip. Please let me know if you continue to have problems with the module after you try these steps.
Thanks
