Lambo 4.0 acting weird

[SGorman1202]

I got my Lambo 4.0 from Myvaporstore and recently it's been acting weird. When I click the button to take a puff, it starts telling me the ohms of the attached cartomizer. I know if you click that button 5 times it's supposed to do this, but I am only clicking it once. And when it does this, it doesn't fire up. I have to push the + or - button and then push the activation button again to get it to fire up. Then the next time I want another puff, same thing happens. I have only had this for maybe 2 months. Help please. I really don't want to replace this.
