OK further info.

If I kick off with Tidal on ControlPC everything is fine but if I transfer to C15 same problem C15 goes into reboot loop.

Power cycle MD600 running core and C15 gets me back to square one.

If I kick off with Sooloos TouchPC (C15 Skin Client) it crashes on PC and if C15 is on and is active or passive it goes into a reboot cycle.

Hope this information encourages comment from those far more knowledgable than me. mad cry
