After effect problem [overlay]

Hi all, i’m using the tirial version of trapcode Shine:

I have a layer that contains a 3d animation with aplied shine efx.
Above this i have a photoshop made lines (imported like psd).
Now i want to give to this last layer the blending mode “overlay” but it did not wonts to take it.
I aplly overlay but it did not works. Seems the pverlay works only if i have under an image or some still. Not with an animated shine affected layer.

Anyone can help?
