Error: Unable to preload audio on AMA linked AVCHD

Hello all, I have recently upgraded to MC 6.0.3. I am currently using this on OS X 10.7.4.The sequence is 1920×1080, 24p. There are two streams of linked AVCHD files with audio (one is 24p, the other is 1080i at 29.97), plus 4 tracks of linked .WAV audio files. Can someone please explain why I am getting this error? Thank you in advance.
