Multi-DB Setup Successful, But Now WordPress Unable to Select the wpglobal Database

I *think* I successfully set up Multi-DB last night. The last step in the instructions all marked green-text "Exists" as well as green-text "Table in New DB" by the time I was all done.

But then I visited my homepage at Listiller.com and received the following: Error establishing a database connection.

If i try Listiller.com/WP-admin, i get a more detailed error:

"Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the wpglobal database.

Are you sure it exists?
Does the user diablo2_wrdp5 have permission to use the wpglobal database?
On some systems the name of your database is prefixed with your username, so it would be like username_wpglobal. Could that be the problem?

If you don't know how to set up a database you should contact your host. If all else fails you may find help at the WordPress Support Forums."

Why do you think this happened?

Should I simply create a new database called diablo2_wpglobal at the root of localhost? If so, will it impact my whole Multi-DB setup?

Thanks guys!
