Point-blank has been known to have random problems in the past, and seems to be mostly unmaintained these days (as in the operators have sort of stopped caring about it, I guess).
If your torrent is trying to track from point-blank, then you downloaded it from point-blank or somewhere else. Remote it from your client, and re-download it from gotwoot (
http://www.gotwoot.net/wp-torrents.php?s=1 ), and your problems will go away.
In other news, this probably goes in "support" ... so I moved it there >_>.
