Subdownloader crashes after start

Hi there,

are there any known issues with SubDownloader and Windows Vista x64?
Everytime I start SubDownloader it instantly crashes.

The stderr.log says only "Subdownloader started" (nothing else in there)

The application error protocol reveals:
Fehlerhafte Anwendung run.exe, Version 2.0.7.0, Zeitstempel 0x48554bd0, fehlerhaftes Modul QtGui4.dll, Version 4.4.0.0, Zeitstempel 0x4815d5a9, Ausnahmecode 0xc0000005, Fehleroffset 0x0005ddea, Prozess-ID 0x16dc, Anwendungsstartzeit 01c94249e55c2f6d.

Sorry it's in german, I'll try to translate:
Fehlerhafte Anwendung = failing application
Zeutstempel = timestamp
fehlerhaftes Modul = failing module
Ausnahmecode = exception code
Fehleroffset = error offset
Anwendungsstartzeit = application start time

Any help appreciated.

Regards,
Basser
