Hey, don't be so impatient. You may have to wait more than three hours for people to help you out on their free time. I don't think anyone at Arturia is working early in the morning on a Saturday...
If you have the USB cable plugged in it should turn up as two MIDI devices, of which only one is functional (I have no idea what the second one is for). Connect the Line Out of the Microbrute to the Line In on your soundcard and set up a track in your DAW to receive signals from the audio channel. Turn up the volume on your Microbrute, set up the basic patch as described in the manual, play a few notes on the keyboard, and you should get sound from it.
