Installing Drupal

Please help

I've accidently changed the name of the drupal admin user to some other name with non-english characters, then logged out and tried to login again. Now I can't login.

How to login as admin user? Or how to make a new user with admin permissions?

Just downloaded drupal 4.52.. and installed, tried to browse to it, got a rough black and white text page of drupal with the login and pass box. It stated that the first login was the administrator blah, blah.. I put in a name and pass and the took me back to the main site's homepage ??

I'm looking to branch out my existing website (http://WickedSunshine.com) so I'm trying to set up / test Drupal without replacing my current site just yet.

This is my first install and when I test http://www.WickedSunshine.com/Drupal/ I have the following error:
Navigation
Page not found
home

I think it may be from one of the following reasons:

I am loading drupal on window xp. I have installed the following versions of software:

apache_1.3.33-win32-x86-no_src.exe
php-4.3.10-installer.exe
mysql-4.1.10a-win32.zip

I tested with a sample php file connecting to Drupal database. It is working fine.

I downloaded drupal-4.5.2.tar.gz and extracted the contents to:
C:\Program Files\Apache Group\Apache\htdocs\drupal-4.5.2
I have made the following changes to:
C:\Program Files\Apache Group\Apache\htdocs\drupal-4.5.2\includes\conf.php:

$db_url = "mysql://devuser@localhost/drupal";
$base_url = "http://localhost";

I have copied C:\Program Files\Apache Group\Apache\htdocs\drupal-4.5.2\index.php to

C:\Program Files\Apache Group\Apache\htdoc\index.php.

But when tried to access: http://localhost/index.php

I am getting:

Warning: main(includes/bootstrap.inc): failed to open stream: No such file or directory in C:\Program Files\Apache Group\Apache\htdocs\index.php on line 12

Warning: main(): Failed opening 'includes/bootstrap.inc' for inclusion (include_path='.;c:\php4\pear') in C:\Program Files\Apache Group\Apache\htdocs\index.php on line 12

Fatal error: Call to undefined function: drupal_page_header() in C:\Program Files\Apache Group\Apache\htdocs\index.php on line 13

Questions:

Is this directory correct:
C:\Program Files\Apache Group\Apache\htdocs\drupal-4.5.2 --> should I extract the file to --->htdocs\drupal-4.5.2 ?

I've been working with drupal for a bit, and ran into a problem today that i've never run into before.

I loaded a handful of modules in, no problem, but later I was needing to add some more (Case in point was when I tried to load Amazon_Items) the page begins to load... and abandons. I get a blank page-- it doesn't even load the . I'm completely not sure where this is going, or how to fix this. I've been reading through /var/log/httpd/access_log and it's not giving me any help... Any idea?

I have and existing website (http://WickedSunshine.com) with HTML content (except for PHPCounter and Coppermine Gallery) and I'm looking to branch out. After narrowing it down to TikiWiki I changed my mind to instead try Drupal on recommendation from my web hosting service (http://LaughingSquid.com).

(I would love to hear any commentary or criticism on the pros and cons of TikiWiki vs Drupal, or anything similar. Perhaps there's a good site that debates this?)
