I have this keyboard: BTC 9019URF, but now all of a sudden it doesn't work. I have no idea why either. I've re-installed the drivers at least 3 times, and i've tried this on my pc, and 2 other laptops. I'm about to go try it out on my PS3, but aside from that, is there anything I can do to fix this? Or is it not software and its just broken?
