Yup, know bug.
Others may have more ideas, but the only thing I can suggest for now it to skip Prelude till this get's fixed.
Thanks for the note Jim... another quick question. How will I know when the bug is resolved?

Also, is there a way to repair the audio without remaking the sequence?
There may be. Do a forum search, I think I read a work around for this a couple weeks back or so.
