Cool, good to hear! In the meantime, I've rolled back to the Cinema 4D Siggraph demo and have my SpaceNavigator working again. It's very difficult to go back to the 1, 2, 3 keys for navigation once I've felt this freedom!
And FWIW I've found that I feel most comfortable navigating when I set all the axes at their defaults, set C4D to Fly mode, and then in the OS X preference pane -> 3Dconnexion -> Device tab -> Zoom Direction, set it to the unnamed second option with the blue arrow going in and out. Once I did that I no longer had to futz with trying to invert individual axes, as everything more or less felt right.
Now it's September, so let's hope the official release shows up soon!
