Best thing to do is a clean install: delete everything and try again.

The Wordpress MU forums are good for this, a 5 minute google search came up with this:-

have you entered the correct data ( database name, username and password) in wp-config file? rechek it.
Also if your host have fantatisco, you can try that for installation.
