DDJ SZ unable to connect as audio device

Up until today I have been using RB 6 just fine with my DDJ SZ. Now when I open RB, I am unable to connect my controller as an Audio device. It's showing up that it is connected via USB, I can select it as a line out and be limited to 1 channel, i can still controller the playlists with the search knobs... but when i try and connect as the audio device, selecting the PIONEER DDJ-SZ ASIO, i get nothing. It returns to No audio device.

I've tried uninstalling and reinstalling the driver but I've had no luck.
