I am trying to load music on hold on to a BCM 50 R6. The music file I know is compatible since I have used it on other systems with success. I can upload the file. When I try to add it to the playlist I get a error pop up message as follows: "PlayList Add Failure; List output error. Update Cancelled" The end result is that I cannot get the sound file to play. For my browser I tried old IE, Firefox and Chrome. I am using a WinXP PC. Not sure where to go next.
