PRJ0002 error result returned from 'cl.exe'

[crazyIvan via DotNetMonster.com]

Here is the situation, all my code on my machine was working fine. I was
trying to make some game shaders work properly and installed the latest
version of the DirectX SDK. Now no matter what I try to compile I get this:

------ Build started: Project: test, Configuration: Debug Win32 ------

Compiling...
test : error PRJ0002 : error result returned from 'cl.exe'.

Build log was saved at "file://c:\Documents and Settings\Robert C. Sharpe\
Desktop\test\test\Debug\BuildLog.htm"
test - 1 error(s), 0 warning(s)


---------------------- Done ----------------------

Build: 0 succeeded, 1 failed, 0 skipped

I'm running Microsoft Visual Studio .NET 2003 and three days ago everything
worked, now nothing related to C++ works, I haven't tested any other
languages mostly because C++ is a top priority. Any help with this or any
information would be much appreciated.

Thanks
