So when I try to connect my Nikon D300s it crashes SGP 3. I have read that I need microsoft redistributable and I have downloaded them and it still crashes. I do not know where these files should be stored. I also have read that I need SDK files or md3 files and I don’t know how to obtain these or where they should be stored. I tried the nikon application for SDK files but apparently my email address is not acceptable since it’s a free email. Any help on this would be greatly appreciated. It may also be worth noting that I am very new to windows and SGP.
