It sounds like things did not properly install and maybe some of the files are missing or extensions disabled.
Can you check:
* That the /libraries/sourcecoast/utilities.php file is present on your system?
* In the Extensions Manager, that the 'SourceCoast Extensions Library' is enabled.
* In the Plugins Manager, that the 'Authentication - JFBConnect Social Integration', 'System - JFBCSystem', and 'User - JFBConnect Social Integration' plugins are enabled.
