I'm not sure.
The way I understood, it is a free script with no tech support. I paid someone to install it and answer questions for me.
The username and password are to access the DB on my server.
Either way, there is a message board. Its not very active, so some times it takes a day or two for a response.

wish I could help more, but my knowledge is very limited.
