Front End Editor activate error

I have been trying to activate this plug-in but everytime I do it gives me this error.

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /home/sites/ocd.co.uk/public_html/wp-content/plugins/front-end-editor/scb/load.php on line 21

Here is the code which i think it is talking about

if ( !class_exists('scbLoad') ) :
class scbLoad
{
	private $data;

	function __construct($file, $rev)
	{
		$this->data = array(
			'rev' => $rev,
			'path' => dirname($file),
		);

P.S I am not that good with programming so any help or advice would be brilliant.

thanks
