Solving MathWorld SpecialFunctions Error in Mathematica

[ehrenfest]

The title should be "mathematica problems". Can someone fix it?

When I execute the line

<< Utilities`Plot`

I get the error:

Get::noopen: "Cannot open \!\(\"MathWorld`SpecialFunctions`\"\)."

I download the MathWorld package which contains the SpecialFunctions notebook and I put it in all of the Mathematia directories I could find and the error message would not go away. Grr...

OK. So let me ask a more general question: Does anyone know how to install an add-on for Mathematica 6.0?

OK. I think I fixed this problem.

Now, does anyone know how to evaluate a contour integral with mathematica 6.0? Is there a package that does that?
