HI,
Check the Nikon website for a 10.6 (Snow Leopard) compatible software. It says: System Requirements
10.5.7 or later here:
http://www.apple.com/downloads/macosx/drivers/nikonviewnx.html But that doesn't necessarily mean it's compatible with SL.
Try here for product support.

Try repairing disk permissions also.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
Carolyn 🙂
