LXmini MiniDSP 2x4HD Problem

Hello,

Several years ago I acquired an LXmini variation made by Beanstalk Audio (mentioned about 1/4 way down this page). I am the second owner. They worked perfectly for a few years in a family member's system, and then were put in storage for at least a year. I am now wanting to use them in my own system but when I hooked everything up there was no audio coming out of the miniDSP 2x4HD. I have set them up successfully a few times in the past and I confirmed that all other parts of the signal path were working correctly.

While unsuccessfully trying to get music, I did poke the reset/control button a few times. I don't know what this did, as it's not drawn or described in the user manual, and is only labeled on the PCB drawing.

I've now downloaded the $10 plugin for the device but my macbook isn't seeing it to connect and I can't locate anywhere to download the config files for the LXmini. I also don't know how different the Beanstalk config would be to the stock LXmini.

Does anyone know what's going on with the miniDSP? I suppose it could have just gotten damaged somehow in storage. Any suggestions for the quickest way to use these speakers without too much monetary investment? Also, does anyone know how to contact Ben from Beanstalk/Ono? I had an email and phone number from 2016, but neither worked.
