Problems with Cudaminer on GTX9800

[jdarkslayer]

I have an old card that I had just laying around that I thought I would just put in a spare computer and try and get working.

First the details of the rig. It is running Server 2008 r2 x64 and I have the latest NVidia driver installed. I am remoting into the computer over my LAN.

With the newest version of Cudaminer I start it and am getting a unable to query CUDA driver version! are you sure you have a nVidia driver install?
Pulling up device manager it shows the GPU and the driver installed. Don't really know where to go from here, have tried searching for this problem and reading though the readme file but I can find nil on how to fix this.

You need to download and install the CUDA development kit.  It contains the CUDA libraries the program needs.
