Downloadproblem

Hallo, ich weis, man wird hier meistens gleich mit faulen Eiern und Tomaten beworfen, wenn man mal einen (fast) kompletten code, postet. Aber ich weis in diesem Fall nun wirklich nict wo der Fehler liegt:

Meine Klasse Download lädt ordnungsgemäß die gewünschten Datein runter und speichert sie. In meinem Beispiel ein video von 1.2 mb Größe. Das konnte ich auch 10mal hinschreiben, also 10 Downloads separat starten und es hat alles einwandfrei geklappt. Wenn ich es aber nun so mache, wie ich´s halt mache, also mögl. Downloads auflisten, wählen, anzeigen und runterladen auf Knopfdruck, dann kriege ich immer nur 642 Bytes vom Server geschickt. ICH HABE KEINE AHNUNG WARUM!!! Kann mir evtl. jemand helfen?
