Convert to DNG is disabled in the Get pictures from camera

I use the latest version of brigde CS3 with the last update (2.1.1). I normally convert my NEF-files for NIKON D200 to DNG during transfer from my camera. After updating the camera RAW-plug in to 4.5, the convert to DNG-tickbox is disabled.
I have not found anything like this in the user fora. Maybe I haven't looked enough?
I use Windows Vista Home Premium edition.
Anybody have a suggestion? Should not Adobe check that their updates are synchronized in the creative suite?

Regards!
