Paper towel method works really well... Keep it in a warm place and your set. Maybe just a dud seed
Why do you say its dead now? after only two days?
You should be putting it in 4 layers of paper towel on a plate, 2 under it 2 above it. fully soaked with room temp water, then let it drain off, lean it at a 45 degree with something covering the light, and in a warm place, youll germinate 100% of viable seeds doing that
