Trouble accessing off-line Help function in Visual Basic Express 2008 II

Question

I'm having a little trouble with accessing the off-line Help function in Visual Basic Express 2008. I can't access any information on it for some reason and keep getting the following error message: "No topics could be located that were relevant to the F1 request". Any ideas as to how I can get around this?

I have already tried, without success, a number of suggestions from an earlier thread I started in the Visual Basic Express Edition forum including downloading and installing the MSDN Library (as opposed to using the one I obtained on CD)

I'm running Vista SP1
