Error when try to run VB form.

I'm keep getting this error when I try to run a form created in the
visual builder:

Error in setup resource: Illegal 'owner' reference passed to
Prima::Window::init at F:/Perl/site/lib/Prima/VB/VBLoader.pm line 136.

Is it because I'm using build 808 instead of 806?

prima_test2.pl
#------------------------------------------------------------
use Prima;
use Prima::VB::VBLoader;
$form = Prima::VBLoad( './prima_test2.fm' );
die "$@\n" unless $form;
Prima::message("Error in setup resource: $@");
return;
#------------------------------------------------------------

prima_test2.fm
#------------------------------------------------------------
# VBForm version file=1.2 builder=0.2
# [preload]
sub
{
        return (
        'Form1' => {
                class => 'Prima::Window',
                module => 'Prima::Classes',
                parent => 1,
                code => Prima::VB::VBLoader::GO_SUB(''),
                profile => {
                        width => 104,
                        sizeDontCare => 0,
                        name => 'Form1',
                        origin => [ 490, 412],
                        height => 100,
                        originDontCare => 0,
                        size => [ 104, 100],
        }},
        );
}
