i cant open a torrent file

Hi B-Don,

You must register at http://torrentzilla.org/ first, because it's a private tracker.

A private tracker is a tracker which requires registration at the tracker website before you can use the torrent. This means that registering at Mininova won't help! Such trackers usually have a high amount of seeds, because users get banned if their ratio is too low. See for more information the Wikipedia entry regarding private trackers. (http://www.mininova.org/faq.php#pt)

When a .torrent file is downloaded from one's account, the passkey is automatically added to the announce URL in the .torrent file. Therefore whenever that .torrent is used the tracker will associate it with that account.

In order to prevent .torrents from being uploaded to public sites (in effect turning this into a public tracker), there are a number of security measures in place. For example if, at any time, there are more than 5 distinct IPs simultaneously using the same passkey with the same torrent, the account associated with the passkey will be automatically get a new passkey. This will also invalidate all torrents with old passkey!
