I have the same problem. It is my understanding that Adobe does not plan to provide an updated plug-in that is compatible with CS2. In order to get a plug-in that works with the D300, I was told that I needed to upgrade to CS3 or switch to Elements. I have a trial version of both and the plug-in does work for the D300 RAW with both of these software programs. I like Bridge, that comes with Photoshop CS, much more than the organizer that comes with Elements. Does anyone know if the bridge from my Photoshop CS2 can be made to work with Elements?
