Unable to connect to the controller error when using the TestSuite quick launch icon.

PROBLEM

 

I use the TestSuite shortcut on the desktop that launches Station Manager, then TestSuite, but get the error:

 

Unable to connect to the controller.

 

This does not happen with a different station configuration.

 

 

 

ANSWER

 

This may happen if the station configuration file is corrupted.  To verify rebuild the station configuration file with the same name and replace it.  You do not have to rebuild the entire station right away.  Add just one channel and signal to test it first. If the error goes away, proceed to build the rest of the station.
