Howdy,
I'm using the Pro beta version 1.0.9.8, and I didn't have any trouble at all in opening the file.
I just got to listen to it today - it sounds a lot like some of the exercises that I do for myself when I'm practicing my bass. I sort of try to keep a single theme, and then explore how I can rhythmically manipulate it while keeping in the same "time" frame. So this piece "felt" good to me
More later - kids in tub hollering....
