MySQL Connection Problem w/ MT (mt-load.cgi)

I have MT setup and almost ready to run on my domain, but I am running into a problem with the mt-load.cgi. When I run it it spits out an error saying “Connection error: Access denied for user: ‘’ (Using password: YES)”. But, that is not the host name that I put in the mt.cfg file. I had put in the proper mysql host name for my domain. I know that the user name works with the domain and with the permissions that I have for it since I connected to it with mysql admin tools from my home pc. What can I do to fix this?

Here is the important info from the mt.cfg:
