When I click on .torrent file there is no pop-up window for me to save the file and download it. I dont know how this happen but it worked before.
there could be many reasons for this, I suggest you try starting bit comet and opening the torrent from bit comet.
The popup screen is an option in bit comet which could not be on, or its possible something has change the file assoiations in windows so that bit comet is no longer your default program.
If you are able to use bit comet by opening the torrents from the program, then it is prob working correctly and you should check the Items I mentioned.
