A couple things: try retracting the blade of the plane. Pull it all the way in until it does nothing, then a quarter turn at a time, push it back out. At first it won't do much, but tweek it out until it does enough.

Second, do not hold the plane absolutely parallel to the direction you are pushing it. Hold your plane at an angle to your direction of motion. This lets the plane slice into the wood more gradulally.

If these two things don't work, try sharpening again. If, when you hold the blade edge-up under a bright light, you can see a reflection off the edge, you need to sharpen more.
