Lofted cut guide curve issue

Hi all, I'm having a difficult time performing a particular lofted cut using a guide curve.  I can successfully get the lofted cut to work, but I can't get it to follow a guide curve(I get a "loft operation failed to work").  In the attached picture you can really see the strange route of the lofted cut and the sketched guide curve I'd like to use.

I've also attached the .sldprt file because I'm sure that's the only way anyone will be able to help.

Thanks,

Andy

Edited: I had the wrong file attached.

Edited again: Added a new file.
