MySQL Database connects, but says the name is incorrect

I am trying to install Pligg on my linux server, but am having difficulties. I am at the point where I need to point Pligg to a SQL server, and setup the server on using these instructions:

Pligg asks for:

Database Name

Database Username

Database Password

Database Server Table Prefix

For Database Name, I use mysqld - which Putty confirms is running. I login as root and the password I assigned, set the Server to localhost.

I get this error, however: Error: Connected to the database, but the database name is incorrect.

How can it connect to the DB if the name is not correct? Am I doing something to point Pligg to the wrong DB?

Thanks!

Database name is not the same as process name(mysqld). Leave it blank or enter 'test' as db name; as far as I remember mysql always creates test database by default.
