BlackWidow Ultimate 2016 F6 Key Not Working

So i have a new problem come up and that is the F6 not working properly, but let me explain, I use Spotify as my primary music program and i would always use FN+F6 to start and stop my music and that has stopped working but when i have Youtube open with a video that video will start playing and not the music that i want to play, via Spotify, FN+F5 and FN+F7 work fine for changing songs but F6 does not work, please help this problem is becoming annoying. I have already tried unplugging and plugging the keyboard back in and that does not work, creating a new profile and that using that one does not work either. If you have any idea on what could fix this please help me out, Thank you
