Thanks for writing in! Sorry to hear about the troubles, but would be happy to help!
Has the SoundTouch adapter worked in the past or is this a new addition to the setup?
If it's a new addition to the setup, the software on the adapter may quite a bit out of date on software and the auto update feature may not work. If this is the case, let's see if we can try a manual update to the adapter by following these steps HERE.
