Just make sure you use the Brinkster files, from Snitz Exchange (see link below). Also make sure the database file is inside the pre-existing DB folder.
You should also rename your file, so that anyone cannot download it. Of course, if you change the file name, you'll need to change the connection string accordingly. Probably the best name for the file will be one ending with a .asp extension, like snitz_forums_2000.asp.
You should also make sure that you change the USERNAME part in the connection string by your own Brinkster username.
