VirtuaPin plunger - hardware working but no function in VPX

[rockery]

I have a VirtuaPin plunger kit that worked fine when originally installed in my cab about a year ago.  Since then, I have reinstalled the OS and all pinball software.  The KL25Z board appears to be working fine for button mapping and X/Y movement.  But the plunger shows no response to movement in any games, or in the VirtuaPin controller configuration software.  I have tried resetting the KL25Z with little reset button on the board with no improvement.  I have even returned the plunger kit and board to VirtuaPin and they confirmed it is working properly.   It appears to me the plunger is enabled in both the VirtuaPin controller and in VPX.  A couple of screenshots are attached.

 

As I am new to VP, I am not sure how the plunger signal makes its way from the KL25Z to VPX.  Is there some controller in Windows that processes the information that might have a setting that has disabled the plunger?  I've done a fair amount of searching but can't find any solutions.  Any help is appreciated, including redirection to more appropriate help forums, or a resource that describes how virtual pinball works.

Sorry I cannot answer your question.  But I just redid my build and can no longer find the vitruapin controller software you are using.  Where did you get it from?
