RAW files in PSE

I've shot RAW (.NEF) w/ my D50 for almost a year now. I got the D300 for Christmas and set it to shoot RAW. But now those photos won't open in my PSE (I'm using 6.0). Any ideas??? Help - I need those photos!!!

I've d/l a newer update. Hopefully that will help.

Okay, just ignore me. I got it working.
