Model not Found

[quote author="bobbob" date="1349151254"]Just to clarify you have a file called pessoa_model.php in Application/models that has the model code you posted?

Then can you start without the namespace and see what you get and if you can remove that slash in front of CI_Model that will help.[/quote]

Thank you very much. That was the error. ZendStudio is automatically putting the namespace in the file and that was messing everything.
