David, I'm not sure if this is an old message.  But, just in case you still 
need some help, I tried running your program and found no problems.  To make a 
cylindrical or spherical plot, you first need to execute the following command:
 
    <<Graphics`ParametricPlot3D`;
 
This command will load the standard package ParametricPlot3D.m.
Then, you will need to execute the following command:
 
    SphericalPlot3D[2, {theta, 0, Pi}, {phi, -Pi, Pi}];
 
This should produce the results you are looking for.  If you need a soft copy 
of the notebook that I created, please let me know.
Best Regards,
J. Batista

Hi Dave,

maybe you tried to call SphericalPlot3D before loading
Graphics`ParametricPlot3D`? In that case there are two functions named
SphericalPlot3D  in two different contexts. If you do not want to restart the
kernel, try Remove["Global`SphericalPlot3"];

hth,
Peter
