Thanks for your answer. I managed to install the Google Play Store on the Fire. In this way I was able to install Squeeze Ctrl and SB Player from Google Play Store and do not have to repurchase it
Another question: I have LMS running on a Linux machine which shuts down when there is a certain time of inactivity. When starting Squeeze Ctrl it wakes up the server via WOL which works fine. However, it takes about 20 seconds for the server to wake up. During this time Squeeze Ctrl tries to connect to the server but finally fails, although I have set the server timeout in Squeeze Ctrl settings to 30 seconds. That means that Squeeze Ctrl does not automatically connect to the server but starts with an empty screen and I have to manually connect to the server when it has finished starting (which is annoying since my wife never finds the "connect" menu item which is hidden in the Squeeze Ctrl menu). Is there a way to ensure that Squeeze Ctrl will connect automatically after the server has been restarted? Or would it at least possible to add a big "connect" button in the middle of the empty screen?
By the way, I use Squeeze Ctrl in connection with SB Player. Is it better to start Squeeze Ctrl (which then starts SB Player) or to start SB Player (which starts Squeez Ctrl)? This morning I had the problem that SB Player was not the active Player when I started Squeeze Ctrl (although it was the last used player yesterday evening). So I was wondering why I did not hear any music until I saw that Squeeze Ctrl controlled my (hardware) Sqzeezebox in the kitchen rather than SB Player on my tablet. Could it be that SB player was not yet running when I started Squeeze Ctrl and that for that reason one of my Squeezboxes was selected to be the active player in Squeeze Ctrl?
Thanks for your answers and your great programs.
