Probleme mit Socket Fehler 10061 nur unter Vista?

[SimStar001]

Hallo

ich habe folgende Klasse erstellt und diese funktioniert bei mir super! Habe das Tool dann auch auf zwei Rechnern laufen lassen und es klappt tadellos. Allerdings sind da jeweils Win XP drauf.

Delphi-Quellcode:

unit Livetrack;

interface

uses IdFTP, IdHTTP, Classes, DateUtils, SysUtils, windows, dialogs;

//(const CallSign : String; const Departure_Airport : String; const Arrival_Airport : String; const Current_Speed : String; Current_Altitude : String; const Current_Waypoint : String; const Planned_Route : String; const Squawk : String; const Aircraft : String ; const WakeTurbulanceClass : String) : boolean;

type TFTP = class(TIDFTP)
    end;

type THTTP = class(TIDHTTP)
    end;

end.

im Hauptprogramm führe ich folgenden Code aus:

Delphi-Quellcode:

 form1.Livetrack.download(10000);
  if form1.Livetrack.VID <> 'none' then
    form1.Livetrack.ClearInfoDaten;

  form1.Livetrack.refresh(getRealname,GetATCPosition,'EC3');
  form1.Livetrack.upload(10000);
  SetLivetrackInfos;
  form1.Livetrack.UploadInfoDaten(10000);

Nun scheint nur unter Vista der Socketfehler 10061 zu kommen und ich weiß nicht woran es liegt, da es ja bei mir auch funktioniert und ich denke, der Code ist so ganz ordentlich und ohne Fehler.

Wer kann mir helfen und weiß ne Lösung?
