Accidentally updated to a new build that isn't on the whitelist of Trackers? Have no fear, it's an easy fix.

• Find the version you want here: http://www.oldversion.com/uTorrent.html

• Backup your uTorrent AppData folder, found in here: C:\Users\[USER]\AppData\Roaming\uTorrent or C:\Documents and Settings\[USER]\Application Data\uTorrent for XP

• Install the downloaded file.

• Success, all your torrents should be seeding again.

Suggested builds:
uTorrent v1.8: http://www.oldversion.com/download-uTorrent-1.8.0.html
uTorrent v2.2.1: http://www.oldversion.com/download-u...2.1.25113.html
uTorrent v3.0: http://www.oldversion.com/download-u...ild-25824.html
uTorrent v3.1.2: http://www.oldversion.com/download-u...ild-26821.html

If you have any trouble, just restore the backup and try another build of uTorrent.

@odyssey very helpful thread. Many of us have been there!

Even quicker: go into %appdata%\uTorrent\updates and run the oldest update file in there... 2 minutes tops.
