I bought a Dm14 a few months ago and I noticed that the OOPS wouldn't budge when I used my empire bottle. I could get around it by turning the OOPS on first then putting the bottle on, but I've bought a new FUEL bottle with a ninja reg and it still won't move. I've tried it with 3 other bottles, 2 worked 1 didnt, anyone know why or how I can fix this? The Due tent I should just get a new reg but that's quite a lot of money wasted and how do I know it will work. Thanks
