Acoustic Bridge - Broken

It worked well all through the trial, then then today it wasn’t sending audio.  I was also hearing some of the audio from the transmitting machine.  Checked the settings and it said the trial had expired …ok, made the purchase and input key; the same symptoms.  Uninstalls, reinstalls, reboots, etc and nothing is fixing it.  I uninstalled other software as well; there’s not much on that machine.  It becomes unmuted every half second or so, you can hear the audio at that machine and at no time does it transmit audio anymore.  I don’t know how to submit a ticket for Acoustic Bridge related issues.

This is a wired laptop transmitting to a wired desktop, they're very close, going through 1 switch.
