Cannot get any data from Cyton board [solved]

Hi,

For some reasons, my Cyton board and the Dongle lost connection and I don't know what exactly is the problem and how that happened... Can someone please help me with this?
LEDs on both of them light up, the GUI can finish initialising the communication. But no data shows on the GUI after clicking start data stream.

As I don't know what has happened, I'll provide as many details as I can down here. (I'm on MacOS)

  • I was using it this afternoon and it was fine. It was on the GUI from processing (an old version last modified on Dec 2014). 
  • After that, I was looking at how to stream the data to Matlab through lab streaming layer (LSL). I've streamed the device to LSL several times and attampt changing the channels using "/loc name,of,channels" (I've done the same thing yesterday and it was fine. So I reckon this should not the cause.). Then I found that the matlab (BCILAB) cannot find "EEG" device.
  • Later, I searched online for the latest version of OpenBCI GUI (I cannot remember why I did this). I've downloaded the latest GUI (both the processing based one and the standalone app). 
    • The processing based GUI keep popping up different errors. It was some libraries cannot be found, and now it shows "The function setFont(PFont) does not exist.".
    • So I changed to the app. On the starting page, I checked the status of the device. It says "Failure: System is Down". And of course the GUI didn't show any data, not even those from accelerometer (all showing 0).
  • Then I went back to the old version of GUI on processing. No data is shown on it either.
  • I remember I've clicked the reset button on Cyton board some time this afternoon. I've also switched the dongle to reset once. Can this be the reason?

I've tried trun off Cyton, unplug dongle, then plug dongle in and switch Cyton on again. It doesn't work. I've also restarted my laptop. Still not working. I really don't know what has happened.

It would be much appreciated if you can share your ideas with me on what has gone wrong or how to fix it.

Thanks,
J
