One time my antivirus kept on deleting a suspicious file that was on the torrent and as a result the file was downloaded again and again. So check that also.
1) remove the torrent from your torrent client.
2) Download another torrent having same file (same file structure may with different trackers)
3) open torrent file & give same location as your old torrent.
This is same as forced recheck but it may work for you.
check if there are peers/ seeders having the complete files (100%). If not, find a new torrent.
.also check if the antivirus is not deleting any files. Check the antivirus logs and qaurantine. It can happen that the antivirus is deleting it as soon as it downloads.
this happens when corrupted data is downloaded. Let the download on for 1 hrs at-least and check if it progress any further, torrent clients normally downloads good data and replaces the bad data over time.
and enabling encryption in preferences helps in reducing bad-seeders.
