Really, it should not let you activated it until you configure it. It was an idea from Phinotpi. Essentially, when you configure it you will see boxes appear around the robots that indicate three of their memory locations in multicolor.
Testlund, did it prompt you for anything when you attempted to activate it?
If it did not it may be a bug. It may also be that you must start a simulation first. Let me know what is going on.
