no no... i had this same problem
heres the solution:
go to ur root directory and look for config.php and edit it with a decent text editor.
there should be a part in there that looks like this:
Code:
$dbhost = "";
$dbuname = "";
$dbpass = "";
$dbname = "";
$prefix = "nuke";
$user_prefix = "nuke";
$dbtype = "MySQL";
$sitekey = "";
$gfx_chk = 0;
$subscription_url = "";
now right above that is a box type thing with directions on editing this part.
the error ur getting means that php cant connect to the database or whatever
