Scan returns no result

Hi, I am running WP on a local windows 7 server using XAMPP. I have the latest version of WP 4.1.1 and Duplicator plugin version 0.5.12. When I try to create a new package the scan in step two displays “scanning site” but terminates after 3 seconds with no data returned. It only displays the Archive section with Total size, Invalid Names, Large files etc but no values are displayed. The button for continue to build the packages are missing.
In Chrome under Developer tools I get the following : Uncaught TypeError: Cannot read property ‘RPT’ of null admin.php?page=duplicator&tab=new2:663. The script that is running seems to be (first part) where I have indicated line 663 :

Duplicator.Pack.LoadScanData = function(data) {

var errMsg = “unable to read”;
$(‘#dup-progress-bar-area’).hide();
$(‘#dup-msg-success’).show();

//****************
//REPORT
var base = $(‘#data-rpt-scanfile’).attr(‘href’);
663: $(‘#data-rpt-scanfile’).attr(‘href’, base + ‘&scanfile=’ + data.RPT.ScanFile);
$(‘#data-rpt-scantime’).text(data.RPT.ScanTime || 0);

//****************
//SERVER
$(‘#data-srv-phpserver’).html(Duplicator.Pack.LoadScanStatus(data.SRV.PHPServer));
$(‘#data-srv-wpsettings’).html(Duplicator.Pack.LoadScanStatus(data.SRV.WPSettings));
$(‘#data-srv-webserver’).html(Duplicator.Pack.LoadScanStatus(data.SRV.WebServer));

//****************
//DATABASE
var html = “”;
if (data.DB.Status.Success) {
$(‘#data-db-status-size1’).html(Duplicator.Pack.LoadScanStatus(data.DB.Status.Size));
$(‘#data-db-status-size2’).html(Duplicator.Pack.LoadScanStatus(data.DB.Status.Size));
$(‘#data-db-size1’).text(data.DB.Size || errMsg);
$(‘#data-db-size2’).text(data.DB.Size || errMsg);
$(‘#data-db-rows’).text(data.DB.Rows || errMsg);
$(‘#data-db-tablecount’).text(data.DB.TableCount || errMsg);
//Table Details
This plugin has been working on earlier version of Duplicator. If needed I can issue a support ticket and you could access the server with use of Team Viewer. Please advice.
