Instalation problems

Hi.
I want to try g-dating but when I run the installer,
after entering Database info and write config and press Next I get "The website cannot display the page"

I can see that in the config.inc.php file is updated after Write config.
What am i doing wrong?!?!
please advice me what to do.....

Should be go to next step, but if not, plase send to us at support at grafxsoftware.com a mail with site URL and eventually FTP details to try to fix it.
