Help with Kraken Tourny installing/setup

I cleaned my PC and now my Kraken Tourny edition just wont recognize.. I dont know how to place the product or whatever? never had to do this last time?! I just activated the 7.1 code which i kept ofcourse...

But , nope.. doesnt do anything but offer 7.1 for my other audio devices -.-
why ?

I got latest synapse ect, even tried older versions. I dont know how to register the product? It didnt ask me this first time I dont think...
