Little pb with pause, volume+, volume- and mute button

[Laurentg]

Hello,
I buy MCC today, and it's exactly what I wanted.
However, I have a little problem: some keys don't work (pause, volume +, volume-, mute ...) and that as I did not open the setup menu of MCC server ... without touching anything else, I open the menu I closed it and it works ...
The rest of the features work without i need to start the setup menu, I can find a music, play it, use the stop button (but not the pause button) and adjust the sound but only with sound bar
I'm running windows 8 64bit and TF700

Thank you for your help

Laurent

ps: sorry for my english...
