Remember we told you that last time.

Like George said, you have to crank down your shutter speed. You will have to try different settings until you get the desired effect, but definetly longer than 1/30th for sure.....probably more like a full sec with your cam. That means that you will HAVE TO use a tripod of course. Also remember to lower your ISO to no more than 200. The higher you put it, the more noise it will have.

Keep practicing bud.
