WordPress MU

I get this error on the second step of the install:

WordPress database error: [Duplicate entry '1' for key 1]
INSERT INTO wp_sitecategories VALUES (1, 'Uncategorized', 'uncategorized', '')

The username you chose is already in use, please select another one.
result: error: username used

I can't enter a different user name because there's only one for my database SQL files.

What can I do?

Ok, by changing the files prefix to something other than wp_ i was able to get beyond this point, but it then gave me four database errors and although it told me the WP MU database was set up and sent me an email, the needed files to administer the database are not installed. When I go to wp_inst I get this error:

Fatal Error

Could Not Find Blog!
Searched for fontcraft.com/wpmu/ in fontcraft_db1::eb_blogs table. Is that right?
Please check that your database contains the following tables:
eb_blogs
eb_users
eb_usermeta
eb_site
eb_sitemeta
eb_sitecategories
If you suspect a problem please report it to support forums!

If I try to access the links sent to me in the email I get a 404: File Not Found error.

This is the error I am currently getting.

Has there been any solution to this yet?

I'm receiving exactly the same result. I'm updating to the latest nightly to see if that will help...

I get the same error, but I initially set a different table prefix for my database, wpmu_ rather than wp_.

Also, I get no emails from my domain advising me of login information. (I guess because the "registration" is not going through each time, just stops cold at the error.)

BTW, I'm using the latest nightly, freshly downloaded about an hour ago.

Aack, I just looked at my database in PHPMyAdmin and under Collation, why is the language (?) set to Latin1_Swedish_ci?

I think MU checks the registration name and email account both. Any of them is not unique inside DB will produce such error message. In-order to send E-mail to your mail-box you have to install a mail server in your computer. If you are using a public host, you should not have any problem unless you don't have such service.

I'm getting this same error.

WordPress database error: [Duplicate entry '1' for key 1]
INSERT INTO wp_sitecategories VALUES (1, 'Uncategorized', 'uncategorized', '')

was there a solution? The name definately isn't in wp_users anyway. Why is it choosing "1" to try to insert?

1 is the admin. non?

i found i had my documentroot set wrong.

i fixed this up and went from scratch so it's now installed and nearly working.
