Update

UAS v2

Open UAS in the Webtools interface, find the "Trakt.tv" plugin and click "Re-Install with latest available".

Manual

Dropping the latest Trakttv.bundle into your Plug-ins folder (and replacing the existing files) can result in conflicting files causing the plugin to crash on startup.

We recommend the following steps to cleanly update the plugin:

1. Shutdown Plex Media Server
2. Delete the current Plug-ins\Trakttv.bundle folder
3. Download the latest version of the plugin (available here)
4. Extract the downloaded zip file
5. Move the Trakttv.bundle folder into your Plug-ins folder
6. Start Plex Media Server
