Problem using shortest path function

Hi,

I have a problem using the shortest_path function in my system i am creating. What I am doing is creating an interactive map using dijkstra_sp. When I installed PostgreSQL 8.4 and pgAminIII, shortest_path function was not there, I got the function from pgAdminIII on a linux server and copied it into my pgAdminIII on windows. (I am using windows 7 by the way) When I run the query in OpenJump?,

SELECT asbinary(the_geom) FROM dijkstra_sp('route', 16, 2)

I get an error saying,

ERROR: function "shortest path" in FROM has unsupported return type path_result(PSQL EXCEPTION)

Am I missing certain functions or is there a fault in windows using pgAdminII? I honestly can't seem to find a way around this, does anybody have any ideas?
