Motion 4.0.3 Audio track crashes

Question

I'm animating to a narration track, and therefore have to split/move the audio every now and again. If I touch the audio track Motion crashes.
I've browsed the Motion posts, and saw many posts over the last four years describing a similar problem, but didn't find a solution. Is Motion persnickety about the audio file type? I imported my audio as .mov from a FCP export (not self contained.)
Below is an excerpt from my latest crash log -- only the crashed thread. It looks like Oz is involved. I saw in posts from 2006 that the Ozone plug-in was a problem, but that it seemed to be fixed by updates... which I've long ago done.
I'd greatly appreciate help with this.
Thanks,
Bruce

Answer 1

Thanks Adam. I called tech support. But the guy I was connected to had nothing better to say than it was my problem, since it was my audio file that was the culprit. This despite the fact that the audio file plays fine in Final Cut, and that I imported the audio file two separate times -- once as a .mov and once as .aiff, to new Motion projects. I did this on two different machines, and got the same crashes upon touching the audio file.
I don't see a reason to re-install Motion from scratch since I have the same result on two machines, and other posts have noted the same problem even after re-install.
That said, I would be interested to know if anyone has solved this by reinstalling.
