Error -70066 (NIMC_virtalBoardError) occurrs when you try to send a command to a virtual NI-Motion controller. This happens e. g. when you try to initialize a virtual motion controller or when you try to pass trajectory data to it.
You can use a virtual motion controller in combination with Motion Assistant just to be able to examine existing scripts or to generate scripts on your own. Still the virtual motion controller doesn't simulate a real motion controller. Thus you need a real motion controller to be able to run Motion Assistant scripts. Otherwise you will receive this error.
