There was an unexpected error creating multi database

Ok this is an error I had when trying to ad tables to my database. I am trying to install Multi db because I think and hope my site could get really really large.

Here is my error

SQL query:

CREATE DATABASE wp_000 DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

MySQL said: Documentation

#1044 - Access denied for user 'cpses_lowZreFBKB'@'localhost' to database 'wp_000'

I know I have permissions and I have the username and password. is there any other reason for this to be happening?

Thank you in advance,

Clay
