Ok got the program loaded, replaced the .exe files under \Programs\MSI. Could NOT get the program to even try to play an mp3 file. Then messed around with settings found that apparently this software needs to be paired with my BT headset in addition to the rest of the phone. Had to set my headphones into pairing mode, the program found my plantronics 590a but when I selected it there were no options, no code to enter nothing, just press ok in the upper right hand corner. Pressed ok, went back to the main msi screen saw my headset now listed in the display window (thought I was really making progress here) selected an MP3 hit play, and boom, the program closes and kicks me out to my today screen. After messing for over an hour, it seems like the program and my headset are incompatible. Anyone with 590a out there get this to work or have similar problems? Otherwise it's still dongle time.
