Razer Mamba Wireless

Heyo, I got this mouse about a year ago and its been working just fine, but about 4 months ago the wireless stopped working completely... It works just fine plugged in and has no other issues atm...I've been seeing a lot of people saying update the firmware, so i did that and no change... I've also seen people say that this is a common occurrence for this mouse, but i cant find answers anywhere... Help please!!!
