I wondered whether you now have the correct settings for DNG4PS.
I have not been able to open the 00.dng files in photoshop, but UFRAW is fine. I tried to have the files saved in the same dirctory as the jpgs so as to download them (and delete them afterwards), but this corrupted the numbering, setting it back to 0!. However, you can save the files in dng format, but with jpg as the file extension. In this way, CameraWindow finds and can download them-they just have to be renamed manually. How did you resolve this issue?
