v4 trial - conf file is 0 bytes?

[Naits]

When i try to log in I get the following error;
Fatal error: Call to undefined function curl_init() in /home/bilforum/www/vivvo/lib/vivvo/service/check.action.php on line 39

And I also noticed that the conf.php-file i 0 bytes?
Thats not right, is it?

Did you chmod 666 to /conf.php file? Or, second guess - does your server support cURL?
