Error after installing

Hello,

This error occurs both, on the backend and on the homepage itsel after installing the map
Fatal error: require_once() [function.require]: Failed opening required '/homepages/22/d436030678/htdocs/joomla_2.5/components/com_gmapfp/models/gmapfp.php' (include_path='.:/usr/lib/php5') in /homepages/22/d436030678/htdocs/joomla_2.5/plugins/content/gmapfp/gmapfp.php on line 17

I only see this message. So backend and frontend don't work. I had to delete via FTP sothat my homepage works again. Anyone knows a solution?

HI
please, could you precise the version and configuration gmapfp and joomla
