this deoends on if you are using XP. If your using XP I can help, but if you are using something else, you'll have to contact bit tornado makers. OK, what you should do is right click the file and selct "Open With" and then hit select program from list, and then select Bit Tornado. Then after you do this any other Bit Torrent file you will download should automatically be directied to bit tornado.
Hope I could help
