To allow BBRemote to connect, make sure that Band-in-a-Box Server is running on your desktop Windows PC. You need to have a program called C:\bb\bbhelper\BandInABoxServer.exe running. If it is running, you will see a musical note icon on your Windows system tray in the right lower corner of the windows taskbar. You can run or install the server from the main Band-in-a-Box Windows program, using the menu item Windows | BB2Go.you need to have BandInABoxServer.exe running in the system tray- sees pgmusic.com/help102 for details)
