phpmyadmin... access denied

I've just tried installing phpMyAdmin but it looks like I did somethin
wrong.

How did I install:

1. Installed Apache 2.0.48
2. Installed php 4.3.4
3. Installed Mysql 3.23.58
4. After installing Mysql I ran winmysqladmin.exe and created a username
Timmers and password yyyyy

I now have a folder on my computer called C:\webserver and in this folder I
have 4 other folders, apache, php, mysql and www (localhost). In the folder
www there's a folder called phpmyadmin-2.5.4

5. I opened confiq.inc.php and filled in the following:
$cfg['PmaAbsoluteUri'] = 'http://localhost/phpMyAdmin-2.5.4/';
$cfg['Servers'][$i]['user'] = 'Timmers'; // MySQL user
$cfg['Servers'][$i]['password'] = 'yyyyy'; // MySQL password (only needed

Then I typed http://localhost/phpMyAdmin-2.5.4 into my browser and got the
following error:

MySQL returned:

#1045 - Access denied fot user: 'Timmers@localhost' (Using Password:YES)

Does anyone see the problem? I'm very new to this and I'm guiding myself
with a document I found on the web. But maybe the document has an error in
it somewhere. Please help.

Thanks in advance
