Gil HA Tembel, I checked your problem on Data Center manchine , and there is a problem with using % sing in system command. I installed the latest version of ActiveState Perl 626. and now the problem is solved. here is the link to site which I downloaded the installation file. http://aspn.activestate.com/ASPN/Downloads/ActivePerl/index/ you should download the : ActivePerl 5.6.1.626 -> Windows -> MSI attachment. Now everyone knows that you a big Perl Tembel.
