Belated use of Plex Pass

I intended to set up a NAS some 4 years ago. To this end I purchased a Plex Pass. I have the email from PayPal confirming my payment but cannot find an email from Plex giving me my login details.

I am now, belately, going to experiment with a NAS and have downloaded Windows Plex to a laptop. It seems I need to login by email.

Where do I go to from here to get Plex NAS running?

Any advice Please?

As above, the user/password you logged into the forum with should be the one you are looking for as you have the Plex Pass badge on your user account.

Ok thank you.
