Nautilus X glass not coming off

I got my new Nautilus X yesterday and I tried to undo the glass from the tank and it just won't come off. I tried to twist and turn and pull and push, it just doesn't want to leave the base. I also put the tank in hot water for a while hoping the metal would expand and then I can get the glass off.
Any suggestions?
