Hello WayneState,
Welcome to the NI Forums. The error message should say something like this "Possible reason(s): Measurements: Device identifier is invalid." This means that the name of your device was incorrect. You should use the drop down box to select the one is configured in Measurement and Automation Explorer (MAX).
There is very valuable information in
this site since it is designed for people starting with data acquisition using our products.
Finally, I see you have other problems in this
LabVIEW thread that suggest that you have already overcome the error in this Thread. If so, please post back your description of the resolution and if not, please feel free to post back some screenshots of MAX and LabVIEW.
