i get an error message when i try to use this template.

Warning: include(/images/system/system.php): failed to open stream: No such file or directory in /var/www/web142190/html/templates/at_constructionflex_free/index.php on line 91

Warning: include(): Failed opening '/images/system/system.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/web142190/html/templates/at_constructionflex_free/index.php on line 91

The domain that i use contains a german "ß" - maybe this is the reason?
