WPViewPDF (plus) does not save PDF

  • I've got a big problem.
    After a couple of DLL update, now my software, without change, does not write PDF.

    It's a delphi 5 project, and I (should?) have a PLUS license

    Here's a very simple example

    Code
    unit main;interfaceuses  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,  WPViewPDF3, StdCtrls;type  TForm1 = class(TForm)    Button1: TButton;    WPViewPDF1: TWPViewPDF;    procedure Button1Click(Sender: TObject);  private    { Private declarations }  public    { Public declarations }  end;var  Form1: TForm1;implementation{$R *.DFM}procedure TForm1.Button1Click(Sender: TObject);begin   WPViewPDF1.ViewerStart('', 'Franco Corbelli', 'XXXX-XXXX-XXXX-XXXX', 12345678);   WPViewPDF1.loadfromfile(extractfilepath(application.exename)+'1.pdf');   //ShowMessage(inttostr(integer(wpviewpdf1.plus.enable(0)))); // result 0 (not enabled!)   //wpviewpdf1.plus.SetSecurityMode(0); // without luck   //wpviewpdf1.Plus.SetSecurityPFlags(255); // no effect   try   WPViewPDF1.plus.savetofile(extractfilepath(application.exename)+'2.pdf');   except       on e:exception do           showmessage(e.message);   end;end;end.

    Here the example PDF

    Where is the problem?
    Seems to have "lost" PLUS function!

    PS in same directory
