Nope, can't open that PSD in Photoshop CS2.
But I was able to export mine out of Paintshop Pro as a PSD.
It will look the same but it won't have all stoic's layers included in it. His will be as a single layer, with mine on top of it.
You can download the PSD, PSP, and JPG
here.
You can copy those layers from my PSD over to stoic's, being careful to make sure they are in the same order and the transparency settings are the same.
