I had nothing but fucking problems with CS2. Dunno what your downloading capability is, but I would grab CS3 post-haste - I had zero problems using that. My question though is, are you doing enough RAW-tweaking in Camera Raw to make it worthwhile? Picassa can open RAW files, and then open a JPEG/TIFF/W.E in CS2 - doesn't have the pre-post-processing power, but it should suffice.

CR2 is Canons RAW file format (I dont think theres actually a .RAW file extension). On the D80 its .NEF. You may just have to update to CS3, as CS2 Camera Raw wasn't all that great to begin with, and may not have newer camera file support.
