There are so many similar "problems" already have been issued here (take a look at the end of this thread and you would find posts with a similar situation). There is nothing new to be said about this.
Basic torrent principles:
After you download the torrent, his content needs to stay unchanged (no DELETING, editing, renaming, moving or copying his files, etc.) or you would not be able seeding. Furthermore, his location on a PC needs to stay the same, in the same folder where the torrent has been downloaded.
Last option can be nobody is downloading what you are seeding but...
... or you just played the last hit and run, and now you cannot download anymore the newest OS's which are most suitable for gaming.
You need to figure out by yourself what have you done and whether you had complied with the above rules because the private torrent trackers are working fine for me and other seeders.
