Re: Most plotting not working...?

The usual cause of this is trying to use PlotVectorField BEFORE loading the library. If you've done that, loading the library doesn't fix the problem unless you Remove[PlotVectorField] first. (That removes the Global instance created when you tried to use the undefined symbol.)
