The command PlotVectorField is not defined unless you have first loaded the 
standard package Graphics`PlotField` using either a Get or Needs command such 
as

Needs["Graphics`PlotField`"];

However, it sounds like you are working in 3D in which case you would need 
the command  PlotVectorField3D available by first loading the standard 
package Graphics`PlotField3D`

Needs["Graphics`PlotField3D`"];

You will probably also need the standard package Calculus`VectorAnalysis`

See the on-line help for each of these packages.
