Yet another compiler problem Not able to compile SDK code

I started to read about CUDA and everything worked great to a point. Lastweek, I downloaded CUDA 2.1 and Visual Studio Express. Admittedly, I do not really know the PC world well enough. My environment is Windows Vista Home Premium (32bit).

I was excited when I could run the bandwidthtest executable followed by Particles. Today I attempted to compile bandwidthtest. Everything I have done so far has led to failure. The problem I get is in conversion. I just thought of illustrating the error with particles (as I may have accidentally modified the bandwidthtest project). When I open the solution file (particles_vc90), I get a pop up window that says:

Project file ‘particles_vc90.vcproj’ or a referenced file has failed to load.
Please correct the specified error(s) and reload the project.

The following error has occurred during XML parsing:

File: C:\Users\Sanjiv\Documents\Visual Studio 2008\Projects\particles\particles_vc90.vcproj
Line: 22
Column: 4
Error Message:
Custom build rules file ‘c:\Users\Sanjiv\Documents\Visual Studio 2008\common\Cuda.rules’ was not found or failed to load.
The file ‘C:\Users\Sanjiv\Documents\Visual Studio 2008\Projects\particles\particles_vc90.vcproj’ has failed to load.

I did not see such an error in the posts and so, am posting it here.

Thanks in advance for your help.
