Not sure what mediatemple is (hosting?) but basically the connection details you supplied for the database are incorrect. You usually need four things to connect to the database:

database name

database user

database password

database host

In a lot of cases if the first 3 are correct, it’s the 4th one that throws you. I think depending on the version you’re installing (what version is that?) the database host is not shown by default so you don’t enter it, it’s hidden by something like “Show advanced database settings” or similar. When you click that, you see the database host and the table prefix can be changed.

Is it possible your database is hosted on another server and you need to enter a host name here?
