Firstly i wouldn't recommend using that tracker source, its only an alpha release, not stable and not for a live site at all.
I would start with the most recent tbdev found here,
http://sourceforge.net/projects/tbdevnet/
Then ad your own modifications to it via the Tbdev forum, I and other users will be able to help you doing this..
If you still want to use this source then most likely your error is with the Styles.sql.
Make sure that, it is successfully imported in the phpmyadmin and the details are correct in secrets.php and bittorrent.php
