I have this problem recently and it's really bothering me, my download is stuck at 99.9% (yes, the download is nearly finished), and i get this error, i've run bittorrent as administrator and changing the download location, i also checked the torrent letter if it has a dot on it, found no dot, i just want to finish my download

Have you forced a re-check on the torrent after making the changes?
