Sound visualisation by using light streaks

Hello !!

I feel a bit stupid by posting my new thread (especially because of the quality) but I got problem with light streaks.

I made 6 points
Each is an emitter and it emits particles as halo
Material is set to halo with a color and size
Each point has got location key frame
For each point key frame I baked sound to F Curves

The points works -they move as sound curve “says”
The problem is that the points don’t emit any particles and the material doesn’t work -so the points are not visible
Before I went to Node Editor ewerything was just fine, after editind nodes and baking all stopped to work.

Here is my .blend file

Check it and please help.

P.S.
Check the textures -something strange is going out there … ;|
