Hi there , I bought a razor naga epic a couple of days ago and it worked fine for the first few days until this morning when none of the buttons work, only the scroll wheel, but it can still track perfectly. Also, the lighting will not turn on in wired or wireless mode even though the drivers recognise it as being attached both wirelessly and when it is charging. I have already tried reinstalling the drivers and restarting the computer. I am using OS X Lion if that matters. I would appreciate any help anyone can offer. Thanks.
