@eobox91103 I am not sure if going all the way back to version 2.2.1 will keep all settings (including torrents, etc), I did downgrade to 3.5.5 (build 46552) by downloading it here: https://utorrent.en.uptodown.com/windows/versions installing it, upon starting µTorrent it asked me if I was sure I wanted to downgrade or keep using µTorrent 3.6 (build 46590) which I chose downgrade, it kept all settings and torrents.
Version 2.2.1 can be downloaded here: https://archive.org/details/utorrent_2.2.1_build_25302 , but be aware that I use it exclusively for a anime private tracker that specifically requires this version, it's very old and it's bound to have security issues and bugs, it works fine for me and is much faster connecting and starting downloads than version 3.5.5 (build 46552) but again, I wouldn't personally use it if not for the anime tracker requirement.
It took a while but 3.5.5 (build 46552) has now successfully connected every single torrent to the gaytorrent tracker successfully.
