NEF files not opening in Bridge CS4??

[metalbound]

ive done a shoot in RAW(NEF) but they will not show in bridge CS4. i've updated camera raw to 5.7 & they're showing in that, then in photoshop fine. but in bridge they just come up with a NEF icon. do i need to update something? i use bridge to sort through everything so it's a pain that it's not working.
im rather technologically retard (!!) so if you have a solution, it'd be great if you could please explain it step by step.
im using windows 7 & shooting on a nikon D90.
please help!
