2D Top down pathfinding

I'm using the Astar path finding algorithm by arongranberg but unfortunately i could find out how to use it for a 2d top down game so ive been modifying the code to work with the x and y axis rather than the default x and z, however when the object is rotating its facing at a 90 degree angle to where it should be (picture below), is there any way to fix this?

thanks in advance
