Move along Spline can't set Mesh Orientation


I have been following this tutorial: and have completed it fine. I then changed the cube to a Skeletal Mesh and assigned my Character to it.

Whats happening is rather than the character facing forward along the spline hes facing 90 degrees clockwise. I need to make him face -90 but can’t seem to do it,

Can any one help please?

Kind Regards
