hi guys, dont really know where to put this, so here we are. basically, i got a perixx px3000 in february and i was loving it (apart from a loud spacebar), when a few days ago the blue backlight refused to turn on! i know the lights arent broken, because when i press the volume wheel in the keyboard glows red for a few seconds like always, but the lights wont work if i go into the software.
so i decided to uninstall and reinstall the drivers....... no difference.
however when i tried to play a game, i could not sprint, so i decided to test the shift on google... and it doesnt work!!!!! what happened? is it driver related or is the keyboard packing in?

please help me!
thanks
