I downloaded a few Torrent seeds off SuprNova (nothing illegal) and attempted to download the files (there's about 8 or 9). One or two work, but for the rest I get "Problem Connecting To Tracker - Operation Timed Out" errors.

What's causing this? Is there a way to fix it?

The tracker is having a problem. Either that or it doesn't like your BT client.

Try Yet Another Bittorrent Client.

Several things.
1) The tracker is down. Suprnova, to put it simply, sucks ass.
2) Your ISP has decided to be pricks and have blocked BT traffic or ports 6881-6889.
3) Your router is not configured to pass ports 6881-6889, or your firewall is blocking them. Configure your router to forward said ports to your computer or tell your firewall to open them.
4) The tracker you're trying to connect to requires your IP to be on the 'OK' list. Some BT clients may just report 'can't connec to tracker', while some will actually report a 'You don't have permission' error.

Seeing as how a some of the torrents work, chances are it's #1, with a possibility of #4 if you've got a crappy client.

I get this problem a lot; I usually stay connected and get the download anyway.
