PlotVectorField Package (easy question?)

I am running Mathematica 3.0 on a G3, and having trouble using
<<Graphics`PlotVectorField`

******************************
In[55]:=

<<Graphics`PlotField`

In[56]:=
    (PlotGradientField[{2  x^2 + y, 3 x - y}, {x,-10,10 }, {y,-10,10}]

Out[56]=

 "Graphics`PlotField`PlotVectorField[ 
    	{{4 x, 3}, {1, -1} , {x, -10, 10}, {y, -10, 10},
		{A long list of all the options}] 
     

******************    
??PlotGradientField gives the help information from the package, but it
still won't plot.  ??PlotVectorField returns: Global['PlotVectorField']

I have tried clearing everything, running from inside PlotField.m, and
even evaluating the example pages from the help manual. 
PlotVectorField just won't run.  What am I doing wrong?
