My Janty Stick arrived today. I have reviewed the manual instructions several times and think I've followed everything correctly. I get the blue light (which turns red after 6 seconds). I've inserted a cart into the atomizer and screwed the atomizer into the stick. No vapor comes out when I press the button and suck. I have it plugged into my lap top here (red light is on like it is charging). Do I need to wait for it to charge for a while? What else can I be doing wrong? Thanks!
