you cant use native photoshop files - the alpha channel is pre-multiplied - or the wrong way round for me.
also layered photoshop files include a hidden composite layer - that overrides any alpha information when imported into catalyst.

you need to use png and tiff.
this was explained in some detail many moons ago.
search for png in catvx
