(solved) Why I can't load MY_ libraries?

[quote author="Ellli" date="1306099567"]well, maybe because you try loading library in view and it should be loaded in controller.[/quote]

I thought about it. But

$this->load->library("Form_validation");
and
$this->load->helper("form");

was there in view (template) recently and the form worked.

I did not do backup So I don't know what I could vitiate.

I also try to remove it to controller but same problem.
