I finally was able to get v2.1 after finding a work around an error message where it was not binding to port 9090
Quick fix:
AudioStreamer.exe is actually running in your task tray. Right-click and edit the config file, then save it. Then you can launch the http://localhost:9090. It seems that the initial run of AudioStreamer.exe is not reading the mongoose.conf file properly.
So back to the AudioStreamer.exe still running, it took a time to shutdown till ZERO cpu usage but had to use Task Manager to kill the process. I am not sure if this is to quick load it for the next time it runs or not. But, just to test to see if it would launch http://localhost:9090 again, it failed to start but did not expect it to run.
Any idea why it does not fully exit.
