standard_redirects not working

[Nullifi3d]

I don't understand why my standard redirects stopped working. they were working fine when I created them.

PHP Code:

$vbulletin->url = 'banners.php?' . $vbulletin->session->vars['sessionurl'] . "do=statistics";
if ($vbulletin->options['banner_require_activation'] == 1) {
    eval(print_standard_redirect('redirect_update_activation', true, $show['bannerforceredirect']));
} else {
    eval(print_standard_redirect('redirect_update_completed', true, $show['bannerforceredirect']));
} 


This just prints out either "Could not find phrase 'update_activation'." or "Could not find phrase 'update_completed'."

My phrases are prefixed with redirect. Their varnames are redirect_update_activation & redirect_update_completed. They're in the Master Language, Front-End Redirect Messages & my Product.
