Issue with Upgrade to Dynamis Pro Box

[cjeffery]

I upgraded my working Dynamis Wireless system with a Dynamis Pro Box, an extra controller and a IR receiver and hope someone here can give some  support.

My system worked fine before adding the probox. It now powers up fine, syncs the roster fine to both controllers but when I press stop to apply power to he track the controllers immediately loose communication with the system. Any commands given to the trains are applied so if I push up the throttle before hitting stop to apply power those trains move etc.

I have 3 locos on the layout. 2 Broadway Spectrum QSI Quantum locos and an older no sound DCC equipped loco.

As I stated this worked fine before I added the probox. Has anyone seen this before and can advise how to resolve this?
