Like beginning and errors

Hi:
I do not have nor idea like beginning.
I want to change texts of the image that attached.
I believe that the problem is on when attempt to open the:
Abatis Manager or GK3 PhotoSlide GK2.
it has the following error

PHP Warning: file_get_contents() [<a href='function.file-get-contents'>function.file-get-contents</a>]: php_network_getaddresses: getaddrinfo failed: Host desconocido. in G:webs-grandes-posicionamientosreparacionbarcos.comadministratorcomponentscom_gk3_photoslideviewsmainpage.view.php on line 242
