Adaptive Cruise Control Not Working

Yesterday morning before heading off to the airport I was charging and I got an alert that sentry mode was disabled due to an error. When I got in the car and headed to the airport I double clicked down to get adaptive cruise control and I got the alert saying it wasn't available. I checked the owners manual and none of the usual suspects were active (no seatbelt on etc). One other thing I noticed is that no cars or other items showed on my screen near my car, it was just blank other than my car. I did the soft reset and no change. When I get back I will try the hard reset - any ideas?
