Problem with my MSDN Help Index

Whenever I try to access my MSDN index stuff, there are only a very limited amount of
things that I can actually get help on. Anything else generates this error:

Selection does not appear in current subset,
Please create or choose a different subset.

This is really annoying since I need to use the file to get information on the math.h library
for my class work. Without it, Im pretty much stopped.

Thanks for any suggestions.

I think, MSDN is not fully installed on your machine or if you are using a server , mapping of drives for different parts of MSDN is incorrect.

Second reason can be that you are searching for the keyword in wrong domain.
Ex: A Visual Bsaic command in the help of Visual C++.

When I first started using VC++ on my computer, the help files were working absolutely perfect. Then when I brought up
the help for the pow() command and how to use it, it gave me that error. Ill reinstall it though, see what happens.
