Why is my zeno hotspot is blinking. Its making a beeping noise and blinking in a red instead of green light. And the batteries are full. so i don't get why it's not working anymore. HELP?

A Zeno Hot spot can only be used 80 times. The red light is telling you you have used your 80, 3 minute cycles. So basically it's just trash now..I was really mad when I spent 40 bucks on something this stupid.
