Program not executing

We’ve updated the firmware on our cortex, compiled and downloaded a new program, and when we powercycle the robot, it just runs the program that was previously on it.
What are we doing wrong, what can we do?

Please post the code using the

 tags and describe specifically what the robot is doing (are the motors simply running non-stop, or is it following the motions defined in the previous program?). The more detailed information you are able to provide with this issue, the better we will be able to assist you.

Thank you!
