[Help Wordpress] Parse error on NewRoyalSliderMain.php, line 538

I just uninstalled version 3.0.5 to upgrade to 3.0.95, and got this fatal error when activating it:

Parse error: syntax error, unexpected ',', expecting '(' in (...)/public_html/wp-content/plugins/new-royalslider/classes/NewRoyalSliderMain.php on line 538

---

Line 538 of NewRoyalSliderMain.php looks like:

public static function get_embed_help_block($slider_id) {

There's no ',' in it !

:(
