Dear Support:
More news:
This error message is generated only in polyphonic mode.

And it happens, when you modify the length of the stream in elastic mode.
I guess, changing length irritates the program to find right addresses.
For me it's kind of slowing down the flow, as I have to flip constantly from elastic mode to normal and back. (And wait for rendering to and fro.)

Anyway there is some other bug in elastic:
in any elastic mode there will be a breakdown when you change playbacks start point.
Chose new location - play - ball of boredom - out! Yesterday it happened about 18 times in 4 hours. Every time after a breakdown I send this report to Apple. Do they transfer these protocols to you?

I try to send you the mentioned files you asked for.
Thanks
