Joystick

Hello, I have a Rapoo joystick and it has been working just fine but last week it started acting weird. The way it is supposed to work is when you first turn it on it has two lights that flash for a moment and then when it connects it turns on just one light. Last week it started to go back to both light flashing when I was controlling my robot and when they both flash it doesn't control the robot and then it went back to just one light and everything was okay again. Now it won't connect and both lights flash and it never connects. Anyone have any ideas or is it trash. I tried new batteries and reconnecting the dongle. Also reloaded the driver.
