Issue with the latest wordpress plugin

Just found a problem with the latest wordpress plugin, on the file protection.php line 119 this:

Code:

if(is_category()){
            $cat = @$GLOBALS['wp_query']->query_vars['cat'];echo $cat;
            $cat_settings = new am4_Settings_Category($cat);
            if($settings->{'protected'}){
                if(!$this->haveAccess(am4AccessRequirement::createRequirements($settings->{'access'}), $settings)){
                    $this->makeRedirect($type,$settings, true);
                }
            }
        }

where it should be: $settings = new am4_Settings_Category($cat);

Code:

if(is_category()){
            $cat = @$GLOBALS['wp_query']->query_vars['cat'];echo $cat;
            $settings = new am4_Settings_Category($cat);
            if($settings->{'protected'}){
                if(!$this->haveAccess(am4AccessRequirement::createRequirements($settings->{'access'}), $settings)){
                    $this->makeRedirect($type,$settings, true);
                }
            }
        }

Just to clarify, this bog makes all the archive or category page unprotected, so this is pretty serious.
