error with jfbconnect

Hello and I hope you can help me.
Recently I was getting an error 500 message so I updated the jfbconnect to see if it was that and I am currently not able to see my website I am just getting a blank page. I have had to take it off line.

My website is www.bboytv.co.uk

The error that I am now receiving is

Fatal error: require_once(): Failed opening required '/home/bboytvco/public_html/components/com_jfbconnect/libraries/facebook.php' (include_path=':/usr/local/php56/lib/php') in /home/bboytvco/public_html/plugins/community/jfbcjsactivity/jfbcjsactivity.php on line 13

Im not sure what to do about this and I hope you can resolve this matter.

hope sime one can help
