Blinking light on dynamis reciever

[StevensonDW]

Can anyone help me understanding the blinking green light on my previously great working dynamis receiver.  I purchased a probox and followed all install instructions.  Everything worked great for two weeks, today while running normally all engines started up and pulled forward, I hit the stop, now I have no communication between the handset and receiver and the green light blinks like there is a short on the track, even when I disconnect the track from the box.

anyone ?  Time to send it all back to Bachmann

Steve-

Is there any chance that a button on your handset is jammed and continually sending a signal?

Perhaps check the batteries in the handheld ...

I have checked for stuck buttons, and have changed the batteries.  It still blinks.  With the probox disconnected, the track disconnected it blinks like there is a short on the track.  It has worked great for a year, i hook up the probox and its like everything is shorting out.
I'm not a quitter, calling bachmann now.
