Razer Mamba Elite RGB Wireless Mouse Dead

Hi all, i have a Mamba elite rgb wireless mouse and when i came to use my pc tonight it was dead. the buttons seem to be working fine (including scroll wheel), and rgb lights as well. i have tried plugging the mouse in with the include usb cable but not luck. looks as if the sensor on the underside is dead. i dont recall have the mouse for two years already, but according to the rma page, its not eligible for service. is there anyway to check when the warranty expired. i dont have a copy of my receipt as this would have been purchase more than a year ago. is it possible to get this repaired or buy the replacement parts or am i on the hook to buy a new mouse.
