Downloaded it and updated, but will going back to 3.10 as 4 requires me to use NX Studio 1.4 and the last version of Studio that has worked properly was 1.2.2. Oh well, the Camera is going back to Nikon tomorrow to deal with several Stuck Pixels. I will have to tape a Note to the Camera, not to update from 3.10 to 4 as Studio NX is NFG after 1.2.2.
I was curious as to what the New Shutter Sounds were. I was hoping for a DSLR Sound, and/or an F3 with MD-4 Sound.
It also wiped all my Custom Settings and reset the Image Counter to zero. It will take me a few weeks to get all that reset, if I can figure out how I made the changes the first time
