OK so I got an aspire nautilus mini for free today (my close friend upgraded and gave it to me) and I was using it on my istick 20 watt for a couple hours and then out of no where it started saying no atomizer and it wasn't firing at all and the istick wasn't even reading the ohms it just says 0.0 it so I put it on a Itaste VV and it wont fire on that either I have no idea what to do?
