Are you getting any errors in LabVIEW? What happens whenyou hightlight execution before running the VI? (Hint: Watch thet block diagram when you highlight execution).
Because the error originates from Init.vi, you are likely not getting a connection to the Arduino. Read what the error says and google the number. There is documentation on each error on NI's website that will give you several things to check to try and troubleshoot the issue.
