I have used Tribler for a few D/loads, easy to set up and run plus not too demanding
BUT unless I missed something in the instructions, it scans tinternet not particular sites ,you don't get full info on the torrent and post d/load passwords are sometimes required and fake files download.
Similar to the old limewire I'm afraid
Can you not just alter the setting's / upgrade to newer version. Which i suppose you have done already.
As soon as i can work out what KVM switch I can use with Windows 7, I am going to use an old machine running linux for my torrents. I like Transmission.
