..short update:

I found out a way to un-freeze the players which might come in handy for those having trouble w this machine!

If player 1 or 2 freezes you follow these steps:

1.Press "playbar" and move it forward (remember to have the slider turned all the way down!!!)
2.Press "Pause"
3.Press "exit"(to exit the "playbar" screen)
4.Press "pause" again (unpause)
5.Press "stop"
6.Press "start"

The above procedure is very important as it enables me to continue with my performance without having to restart...still, I'm waiting for O.S. 1.3......
