Why won't my nikon D3000 let me see my pictures?

Its on "NEF (RAW)" I was trying out the setting, and when I went to download it on to my comp.every photo downloaded, that was "FINE" but none of the photos in "NEF (RAW)" did.help? =/ I can still see all the photos and my screen

Ps: I already used a USB CORD and USB CHIP neither work.

Use windows explorer to copy them over. Then download and install view nx.

I had the same problem. Now I use Picasa 3 (you can download it from google for free) and it lets you upload RAW format pictures:]
