I no longer have a server linked to my account

Hi, I’m having troubles with my account and server
Today I had to initialize windows on my computer (also my main server on Plex)
But doing that, windows uninstalled many programs on my computer (Plex included)
So I reinstalled Plex, but when I connected to my account, I couldn’t access my server, so I had to delete it, and now I can’t find how to recreate it
So now the only server I have access to is the one of a friend, but I can’t add my own videos

Could anyone tell me how I can recreate my computer as my main server? I would rather not have to recreate an account, since I just recently became premium with this one…

  1. Don’t use Microsoft Edge, (which is the default web browser after a Windows refresh

  2. perform this procedure https://support.plex.tv/articles/204281528-why-am-i-locked-out-of-server-settings-and-how-do-i-get-in/

side note: After a refresh of Windows, it often happens that your network adapter has your network classified as ‘public.’ You might want to set this back to ‘private’.
