The normal map can't make what a displacement map can do. Take a look from the Top viewport... that is what the normal map is rendered from. If you look from the Top viewport at your model you will see that you can't tell it has any detail on it. If you extrude polys from the highpoly and leave it just like that from the top viewport it will look just like before. You should scale the top polys down... or use bevel, not extrude.
You should also consider that the normal map is just a map... a picture. This map has the power of changeing just the way the light is reflected from a surface... it doesn't affect the geometry in any way. If you look from the side at your highpoly you'll see that there is a very big extrusion there... The normal map can't make something like that from a plane. Even the best normal map with small details on it will look flat if you look at it from the side.
In my tutorial I extruded some faces but in the end I added a smooth modifier, and with that the geometry relaxed and from a top view you can tell that there are holes in there.
Just too see how this works, and also see if you're doing this the right way... try puting just a text on a plane. Make the normal map and play with an omni light in the viewport to see how it looks and what a normal map can do... also add a bump... to have something generated from a highpoly too.
Good luck! I hope you can figure this out. If you still have qestions.... you know where to ask
