When a torrent is completed in BitComet, it says download complete: 100%. I can start and stop, but download says complete. When I go to the file where the torrent was downloaded, I get an error messeage saying the download is not complete. How can I complete the file download when BitComet says it is alreay downloaded? (Error message: This file "xxxxx" has not finished downloading. Do you still want to open this file?)
