I just got notified of an update today for crew chief. I updated and restarted and now it's not working for Assetto Corsa. I uninstalled and reinstalled and it's still not working. I had this issue once before and was never able to figure it out so I reverted back to the previous version. Unfortunately I can't find my previous version to roll back this time.

When I start CC as normal I get the radio check. Then when I enter the car and start driving, silence from CC.
