Welcome, I have a problem with Buzzers to play Buzz Quiz World. I have no idea how to configure them.

I'm doing this:
1. I plug the flash drive from the set.
2. Turn on the buzzer that was burning a blue light.
3. I push the button on the pen until the flashing buzzers.

Unfortunately, all flashing on and off for a while. After activating the game appears on board with the choice of language and then a Buzzer should change the language, unfortunately, none of that.

Please help.
Greetings
Martin
