Can't use a CD/DVD drive!

Hi, I recently installed Vista and despite some problems it's been ok. I've
encountered another problem however, and my DVD drive will not be installed.
Here are some images that describe my problem better:

As you can see, it appears NOTHING will work! I dont think I have the CD,
and even if I did, how would it work? I can't run it anyway. I've downloaded
the same driver from the NEC site and this comes up:

"Target NEC ND-4551A is not found correctly"

The model is NEC DVD RW ND-4551A as seen in this picture:

I'm completely frustrated and the drive used to work perfectly in XP.
Help would be very much appreciated!
Thanks
