can't get ListVectorPlot3D to work.

*********
HELP states: ListVectorPlot3D[{{ {x1,y1,z1},{vx1,vy1,vz1}}, ...}]
generates 3D vector plot from vector field values {vxi,vyi,vzi} given at
specified points {xi,yi,zi}.

But, I get nothing but an empty box when trying this:

pts={   {{3., 0, 0}, {-2.15667, 3.39688, 4.02369}},
{{0.843326, 3.39688, 4.02369}, {-4.19657, -2.394, 4.8314}},
{{-3.35324, 1.00288, 8.85509}, {2.19306, -4.30499, 4.8314}},
{{-1.16019, -3.30212, 13.6865}, {4.4038, 1.98721, 4.8314}},
{{3.24361, -1.31491, 18.5179}, {-1.77692, 4.49277, 4.8314}}   }

ListVectorPlot3D[pts]

I've spent hours trying various options and have never seen a plot yet.
(VectorPoints->All seemed most promising but got nowhere.)
Surely I'm misinterpreting something --can someone please enlighten me 
as to what? Using V7 on XP.

Thanks, Rob
