why wont this work. It worked the last year, and now the motors refuse to run.

This program never would have worked. I think when you rebuilt your program this year you mistook the Set Velocity block for the Spin block. The set velocity command will update the velocity if a motor has received a spin command and no stop/rotateTo/rotateFor commands after it and always update the default velocity a motor will execute other commands with, but it will not start a motor into motion if it has never received a spin command or has received a stop/rotateTo/rotateFor since the last spin command.
