The same issue was present with the raw interface in Photoshop/Photoshop Elements, it had to be updated to support the camera before it could manipulate the files in the NEF format that the D3100 takes.

This might be because the camera is being accessed in PTP mode. I 
thought I saw in one of the links that Poma supplied that PTP access 
doesn't allow the contents of the images to be modified.
