Brand new Kits - Reloading new programs does not work for us

We are working with brand new kits. We are working through the CS2N activity of downloading sample programs in the VEX EDR Movement Badge. The first sample program downloads fine, but we cannot download subsequent sample programs - the old program just continues to run.

Additionally, each time we go to download we have to re-pair our joystick and cortex.

Help, Please


We download the sample program for 1 motor to run at full power. It downloads and works. However, when we go to download the next sample program, the old program continues to run and the new program never downloads. I am thinking we are missing a step in the process - something that allows the old program to not run when the m icrocontroller is powered on and that would then allow a new program to be accepted into the microcontroller.
