drive train

One of my teams drive train are moving opposite one another so that it goes around in a circle. Please advise. Does the motor have to be reprogrammed? Also, fter installing the VEXos utility and updating all the firmware I ran into a problem with 1. The brain keeps twlling me to update the controller to latest version and I already have.

are you running driver control or custom program? the motor can be reversed in the motor and sensor setup on a custom program if you are running driver control go to the config setting under driver control on the brain and you can reverse the motor there… I have the same problem with one of my brains with the controller update…still trying to debug that one.
