The VIs located on the application control palette are primitives and are part of LabVIEW itself. Therefore you can not look at their diagrams because they don't have one.
However the 1003 error means that you are trying to dynamically load a VI that is not executable. I would suggest turning highlight execution on and following the code to see what path is sent into the Open VI reference function.
Once you have the VI that is failing to open go manually open it.
Chances are that it is broken, so see why it is broken. If I remember correctly there is a linking issue in that example, so you can open the VI that is broken and hit ctrl-shift-Run Button, and that should relink it all and fix the issue.
If not take a look at this
