Cross 3.3.10 is broken

I've gone back to V3.1. Observations of V3.3:
1) Some very weird sync behaviour - where it would jump 2 or 4 beats.
2) Mic mix function not responding
3) Output level may be very quiet. Disconnect and reconnect U-Mix and it returns to normal.
4) If no controller connected, Cross crashes on exit.
