wrong style url

When the page loads with the login widget, the chrome developer tool shows can’t find css file:
wp-content/plugins/miniorange-login-with-eve-online-google-facebook/style_login_widget.css

it should be wp-content/plugins/miniorange-login-with-eve-online-google-facebook/css/style_login_widget.css

I detected in code
line 170, class-mo-oauth-widget.php

	public function register_plugin_styles() {
		wp_enqueue_style( 'style_login_widget', plugins_url( 'style_login_widget.css', __FILE__ ) );
	}

should changed to

	public function register_plugin_styles() {
		wp_enqueue_style( 'style_login_widget', plugins_url( 'css/style_login_widget.css', __FILE__ ) );
	}
