Problem mit Audiosynchronisierung

[elchtreiber@…]

Habe versucht, wie in der englischen Anleitung beschrieben, den Ton und das GPX zu synchronisieren.
GPX mit Wegpunkten geladen, WAV geladen und nun wollte ich den Startpunkt verschieben. Dazu habe ich erst die Wiedergabe gestartet, an der entsprechenden Stelle Pause gedrückt und dann versucht die orange Marke mit SHIFT+Maus zu verschieben. Da kam dann dieser Fehler zustande:
