SFTP not working?

Hi,
I am tring to access to do a FTPDir but in debug mode I am getting a black window "24x7 Trace" any idea how I can troubleshoot this issue?
(I tried with sftpc.exe from another supplier and it work fine) Thanks.

//Dim ftp_server, string, "10.100.**.***"
Dim ftp_server, string, "******.****poste.ca"
Dim sasx_user, string, "****"
Dim sasx_pwd, string, "*******"
Dim file_mask, string, "/*"
Dim remote_list, string
FTPConfig( "TRANSFER MODE", "BINARY" )
FTPConfig( "PORT", "22" )
FTPConfig( "FTP PROTOCOL", "SECURE" )
FTPDir( ftp_server , sasx_user, sasx_pwd, file_mask, remote_list )

If you are running ti on Windows 2008 server, the JAL SFTP commands won't work, please use JavaScript job and commands for this task.

PS. There is some unknown incompatibility in a 3rd party library used internally by JAL SFTP and SSH commands and which is manifesting on Windows 2008 servers, we are aware of this issue
