Loft error: cannot knit sheets together

I have seen several other posts about this error, but none of the suggestions worked for me. I am trying to loft three curves to create a solid body, but the loft fails, complaining that it cannot knit the sheets together. The preview looks good, and I can even do a surface loft without issue, but I need a solid body. Any ideas? I have attached the part file.

Thanks,

Kevin
