FYI, the software includes example files in the folder named (oddly enough) examples. That would be where the TD is installed, usually C:\Program Files (x86)\The Tournament Director 3\examples.
The TD should point to statusListener.php or statusListener.asp, depending on what your web site supports (PHP or ASP).
One thing to point out: the statusListener file will attempt to write the status data it receives from the TD to a file in the same folder in which statusListener is. It is common that this is not allowed, due to file system permissions. You can either adjust the permissions on that folder to allow it, or modify statusListener.php (or statusListener.asp) and TournamentStatus.js such that they use a different path where permissions are different (many sites will have a tmp folder to which data can be written).
