Warning: The loft would flow in an invalid direction.

I'm trying to make the wing tip of an airplane wing, and when I try to loft this it says

Warning: The loft would flow in an invalid direction.
Try adjusting the continuity settings. If two adjacent profiles are on the same plane, try moving one of these.

How do I go on solving this problem?

Need the file, 

not enough construction, would expect top / bottom spar profile for a fighting chance.

separate at that profile for front and back halves.

Lofting to a point should be avoided, so looks like a front loft, then top and bottom rear Lofts.

3 in total.

Might help....
