I received a few 1003 Errors a while back...
"The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located. Open the VI in LabVIEW using File»Open and verify that it is runnable."
I can't seem to recall what I did to have the error or what I did to fix the error, but if everything is working fine for you then I'd be happy with that.
