Connecting traktor S2 to djay pro app

I cannot get my traktor s2 connected to djay Pro…Djay pro recognizes my console but then I cannot map it. Even when I press both shift buttons on my console (which turns it to midi mode and hence recognizable by Djay pro) it does not work. Can you please help??

BTW, I am using windows!
