Soo I received a mini dna 40 from the wife for Christmas and im just now able to sit down and start playing with it. Issue number 1 is unless its plugged into the usb it wont even kick on and as soon as you unplug it the screen will go black. Issue number 2 is that ive tried about 5 different atties on it including an atlantis and I get the check atomizer message for every one of them. So am I missing something or is this screwed up from the start?
