Robot Code disappearing in Driver Station

[Arhowk]

Are you sure you're not erroring out in the Riolog? Make sure the Riolog displays "Launching (bunch of wierd symbols)" to ensure you have communication. Other than that, the most likely offender would be a null pointer exception which should display on the driver station. If you're about tog get System.out.println messages, trace through your code and identify which section errors out and you might see that you forgot to initialize a motor or the like.
