Hi! I bought a Vamo about 2 weeks ago and everything was working fine until about 10 minutes ago... it just turned off on me, so i turned it back on, hit it once, then it turned off again, so i switched batteries, turned it on again, i hit it and then it turned off again and now it wont turn on at all with any of my batteries...it doesnt even make the connection that there is a battery in there ( when u put the battery in at first it usually blinks once to acknowlege there is power) does anyone know what might be going on and if so how can i fix this??? Thank you so much in advnace for any suggestions!
