Blackwidow Elite 3 red keys numpad not responding

Hi, I've been having some issue with my Blackwidow elite. When using it works as normal expect for 4 keys: the "l", ";", " ' " and NumLock key. The first three keys next to each other also have a red color instead of a flashing array of colors like the rest of them. Are there some things I can try? I have tried reinstalling the drivers several times, but it does not seem to do anything. Kind regards, Roan
