Module was unable to synchronize events (Error 403683)

Some additional info.

1. If run from LabVIEW "Run" button, the DQMH module operates properly by itself. 

2. If "Start Module" from the "Tester", the DQMH module will start, and then stop (this is not the case if run from LabVIEW), and Error 403683 is returned.

I solved the problem. It is caused by me changing the "External Launch" value of the "Module Admin" object. Once I stop doing this, everything is fine.

I wish that "validate DQMH module..." can tell me that I should not touch the "External Launch" value though😀. 

What exactly is this "External Launch" property for?

This Property lets the Module know if you are launching it using Start Module or you are just Running your Module using Main.vi, the module behaves different in some aspects depending on this proprety.
