Two things:

1: Did you try any of my suggestions in my first reply to your post, regarding the Task Manager, CPU, Resource Monitor etc? You didn't say what your results were.

2: You mentioned: "When I click that box, you can see that the song doesn't start until all four instrument tracks have been generated, but it STILL gets one or two bars into the song and it starts to generate the tracks again."

How do you know that it starts to generate the tracks again? What indicator do you use to verify this?
