Audition - Will not open - cannot access the Documents folder. (iCloud Drive)

Hi there,

So I'm trying to explore the trial of the latest Audition. I'm running Sierra, the latest version - 10.12.1 - and I have iCloud Drive Documents and Data enabled.

When I attempt to launch Audtion, I get an error because Audition cannot access the Documents folder. (Error message below). I think this is almost certainly due to the fact I have iCloud Drive / Documents & Data (which moves the entire Documents and Desktop folders onto iCloud, keeping it integrated with the Finder).

I'm surprised I appear to be the only one with the error, but I guess maybe I'm the only one using iCloud Drive Documents & Data and Audition?

Anyway. I've tried using symbolic links etc, or trying to edit .plists, but to no avail. Please help!!
