Ok, first problem of this project:

When I try to convert my mesh into Sub-D's, I get this message:

// Error: polyToSubdiv1 (Poly To Subdiv Node): One or more edges is nonmanifold.
// Nonmanifold geometry cannot be converted to a subdivision surface.
// To clean up nonmanifold edges, use Polygons->Cleanup with the nonmanifold option. //
// Error: Command polyToSubdiv failed. Open Script Editor for details. //

And when I use the Cleanup option it converts, but I get this:

Anybody know how to fix this?
