Hello everyone, I hope someone can help me out with this problem. I had install Linux on my computer and had Plex running on it.

I delete my OS and went back to windows. Now when I am trying to setup my Plex back on Windows, it says,

"Not authorized. You do not have access to this server.

You may be able to claim it by choosing “Open Plex…” from the Plex menu in the macOS menu bar or Windows system tray. For more troubleshooting tips, see our [support article](https://support.plex.tv/articles/204281528-why-am-i-locked-out-of-server-settings-and-how-do-i-get-in/)."

I went to the article and I was able to get it to work.

I deleted the Regkeys

- `PlexOnlineHome`
- `PlexOnlineMail`
- `PlexOnlineToken`
- `PlexOnlineUsername`
