Recently dug out this old SPI game, and would love to play it on Vassal.

At one point there was obviously a module, but now it says that the copyright holders have banned it , and we wshould write to them to release it for Vassal, but it does not say who it is?

Is is Decision Games, does anyone know or have an email I can contact?

Vassal must have been told to stop the module, with a shot across its bows by someone?
