Hatch Error?

Has anyone seen this masquerade of an error message?

Jumping on soap box...

For the love of Pete, if the software knows there is a problem, kindly tell me what it is using "...twenty seven eight-by-ten color glossy photographs with circles and arrows and a paragraph on the back of each one explaining what each one was..." Is that too much to ask?

Off of soap box.

I have a complex shape (the light blue highlight in picture) I need to solid hatch. The shape selects just fine. There are no gaps or line-over-line conditions. When checking the green arrow I get this...

Please advise if you can.
