Firmware updated and now Demo Autopilot doesn't work

Hi, I’m a new VEX IQ user. I tried the robot as it was “out of the box” with sensors attached and tried the Demo program “Autopilot”. It worked great. I ended up and upgraded the Firmware to v2.1.3 for all the components, but now the Autopilot program doesn’t work as it should. Anyone else encountered this?
