Deathadder Chroma repeatedly blinking

Hi, I got a deathadder chroma a couple months ago off of ebay and it worked perfectly fine until today. It lasted aproximately from Sept up until now 13th of December. The problem with it is that when I plug it in, the lights on the mouse start flashing constantly and its not detecting any input from it even though it is plugged in and its lights are flickering. Its been acting like this all day. If anyone could help I would really appreciate it. Thank you
