Thanks Andy,
I have installed the latest update of Elements RAW 6.3.

This is the conclusion I have reached.
I have just updated to Windows 7...64 bit.
My old sytem used XP...32 bit, everything performed fine. PSE9 recognised the D7000, the D7000's 'picture controls' and also showed NEF thumbnails.
With Windows 7/64 bit PSE9 recognises the D7000 but does not recognise the D7000's 'picture controls' nor show NEF thumbnails.
Nikon do not do a NEF codec for 64 bit only 32 bit....this I think is where the problem lies.

Another confusing factor is that Picasa does show NEF thumbnails.
Nikon do not do a NEF codec for 64 bit.
If you, or anyone else can confirm this I much appreciate it.

The plot thickens.......What I have said above is a load of rubbish re 64/32 bit.
I have just installed ViewNX2 and it shows NEF thumbnails and also recognises 'picture controls'
The problem would now appear to be at PSE9's door.
