i just received my vortex 2.0 with 3.5 ohm. i filled it asnd let it sit for 5 minutes to soak in and it wasnt making a connection when i connected it to my puresmoker V3. i had to screw it very very tightly and i finally got it to fire but it was burnt. after a few drags it stopped firing again. i tried pulling the conector on the bottom out to make it connect but still nothing. i tried to different carts with 2 different fluids(puresmoke 100% PG AND Innovapors menthol 100% VG) with the same results. PLEASE HELP!
