The old quartermaster crashed after two clicks, that it I can’t change my dpi, and the new one doesn’t even fricken detect my keyboard and mouse. And yes, I’ve reinstalled several times, yes, I’ve tried different ports. I’ve tried calling support, but they say my warranty is expired, I BOUGHT THE KEYBOARD TWO DAYS AGO. Their chat support is useless too, can’t even get in a chat, it says, “Your sn is invalid” I LITERALLY SCANNED IT IN. All I want is a ***** solution. But none of these forums even get any responses.
