OK we have sorted it. It was a problem between Photoshop and AfterEffects CS3. There was some layer options applied some layers in the PSD Builds (Darken / Multiply) This caused problems once the layers had been taken into AE CS3. We removed the layer Blend options in Photoshop and this solved the problems. Another way of solving it was to Delete the LAYER OPTIONS in AE from that offendinf layer.
Hope this helps >>>>>>>>
