Could you say what is the problem
WP 3.6.1
Version 3.11.22
http://www.focussup.com/dealers/?1379753810
Plugin is licensed
it stopped working since upgrade
when activated we get this message :

Fatal error: require_once() [function.require]: Failed opening required ‘/home/focussup/public_html/wp-content/plugins/store-locator-le_bkp/include/class.slplus.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/focussup/public_html/wp-content/plugins/store-locator-le/store-locator-le.php on line 128
