Installing Drupal

I have just installed Drupal 4.6.6 on a Mandrake linux box with SQL 4.0.11.a-gamma, and PHP PHP Version 4.3.1. When I click on the 'create the first account' link on the Drupal welcome page I get to the user account page under the register tab. I enter my information and click on the 'create new account'. This of course gives me the following message in the text area:

First off, this is the error message I'm getting:
"Warning: mysql_connect(): Access denied for user: 'xxxx@xxxxxx.com' (Using password: YES) in /home/xxxx/public_html/includes/database.mysql.inc on line 31
Access denied for user: 'xxxxx@xxxxxx.com' (Using password: YES)"

I've checked over and stared at the two lines in sites/default/settings.php a number of times, and can't find anything that is wrong. I've deleted and recreated the appropriate database and user several times just to make sure there wasn't a problem with that, but no luck.

This is especially frustrating because I have sucessfully installed drupal 4.6 on a different website (lets call it site A), and this site (site B) was working until I decided to reinstall drupal to fix a problem it was having.

Basically, the story is this:
-I have to create a website for a university project, but the client was slow in getting us the webspace so I started creating the website on my personal webspace (site A).
-Everything was going great at this point, all working just fine.
-Finally get webspace from client, and thought to save time perhaps I could just copy and paste all the files from the first drupal installation (site A) on my website over to the new website (site B).
-This seemed to work fine until I realized that even though i would start out and log in at the address for the new website (site B), the pages would all redirect to the old website (site A), which was obviously a problem as I am not prepared to host this thing indefinately, plus a variety of other reasons.

IIS (standard XP offering)
PHP 5.1.2
Drupal 4.6.6
MySQL 4.0.16

I'm having no joy with getting Drupal to run and am hoping that someone can point out what I've done wrong or forgotten to do.

I have done a clean install of the database. First time I connect to drupal I don't get any errors by at the top of the page it displays:

It appears that this is definitely a bug in 4.7 beta 6 as it has happened more than twice already.

Everytime I create a fresh new website using Drupal 4.7 beta 6, the first user, who is supposed to be god or god-like, cannot login properly. I have verified in my MySQL Drupal database that the first user (user with id #1) has been properly configured. Initially, I was able to do some config changes. But once I logged out from that superuser status, I cannot log back in. There are no visual clues as to why I cannot log back in but the same anonymous user interface is served. If I put in the same god username but with an intentionally wrong password, the correct "Sorry. Unrecognized username or password. Have you forgotten your password?" message appears. I have therefore concluded that me logging in as god user #1 with the correct password brings out a Drupal bug on new 4.7 beta 6 installations.

After logging in, the "Who's online" block displays something like this:
There are currently 1 user and 3 guests online.
but in reality, Drupal wouldn't even allow me to access /index.php?q=admin, even manually. And the admin menu doesn't even show. And the user login boxes remain. Except for that "currently 1 user" bit, everything looks like I'm being treated as an anonymous user.

Kindly check please. This apparently did not happen in 4.7 beta 5 nor in 4.6.5, but users in this forum are reporting a similar weirdness in 4.6.6.

When I attempt to install Fckeditor, I get a blank area where the editor should be... I've set the permissions ecorrectly, extracted all the main files to the lib folder, and uploaded and enabled it in the modules.

I would think everything would be in working order, but when I attempt to post any sort of content, absolutely nothing is in the area where it should be, not even an error.

I did try modifying where it links to in the module file, but if I modify anything I'll get an empty iframe that says, "PAGE NOT FOUND".

when i finished installing drupal 4.6 (mysql 5.0, php 5, apache 2) and visited the
create an account page and proceed to create the account i got the following message when i click the login button

(i delete the database and try again same thing)
