Are you sure it's trying to redownload it again? Usually what it does first is go through and verify first.

(I see you have BitTorrent. I think when it asks where to put the files, it then says something like 'Are you sure you want to replace these files?' or something like that. Then, when you say Yes, it goes and verifies the files and then goes into seed mode. If you are a bit uncertain about this the first time trying to reseed, make a copy of that folder and put it somewhere safe. Then go ahead and say Yes and you will see what i mean about how it verifies and then goes into Seed mode.)
