K95 RGB A W D stopped working

I Just got my k95 RGB today, and everything was fine until i launced CS:Go and started playing, just a few rounds in the A key stopped working. I Couldn't use it in chat and i just started to strafe to right, after a while that problem dissapeard and instead the W and D keys started doing the same. I couldn't even use either of the keys after i had closed down CS. I had to restart my computer to get it to work again. My firmware is updated to the newest and i have the newest version of The CUA.
