Drupal installation help

[#1]

This is pretty basic but having deposited all the Drupal files the instructions say...
"To run the install script point your browser to the base URL of your website (i.e. http://www.example.com). You will be presented with the "Database Configuration" page."
I enter my address ccgi.username.plus.com and get ...
"The website declined to show this webpage".
What do I need to do?
Thanks for any help.

Is this a php based application. If so login (telnet) to the cshell and run fixphpperms.sh -r to set the correct file permissions.
Does the install instructions specify a file to run?
Did you install it into a sub-directory. If so you will need ccgi.username.plus/com/subdirname/

Thankyou Peter,
fixphpperms.sh -r did the trick.

Did you ever get this to work.  Drupal 6.6. refuses because register_globals is on and I can't turn it off.  So keen to know if you got it all working.
