Error matrix creator


i have the sam error, help me:

I had a working Alexa Pi with no issues at all and decided to get the Matrix Creator. I followed all the steps mentioned here and now with the Matrix Creator its not working at all. The Matrix Creator just has a blue flashing Led and thats it. Do i have to do something else as well apart from the steps mentioned above?
thanks all
