Guitar hero world tour problem

So I got it working just fine and everything, but when I try to play it won't work. It shows that I'm hitting the keys but when I try to hit the notes it won't hit them. The little thing lights up but it won't hit the note and it's every note. Everything works fine except for this. I dunno how to fix it, any ideas on what's going on?

Hello,

And if that didn't work, try checking your in-game settings and see to which key every action is assigned.

Helpful tip if you want to play I would suggest you buy an xbox 360 guitar hero guitar it will help heaps when you play. Much easier then the keyboard.
