Numeric Problem in Wings3D

I'm trying to unfold some 3d models so I can texture them with Tattoo, but on some of the more complex models, it says there is a numeric problem. How can I fix this?

I'm having the problem again. Does anyone know what I can do to fix this?

Sounds like your models are just too complex for Wings to unwrap. You might get a better response if you post on one of the Wings forums.

Okay, thanks.
