After a reboot of my Nvidia shield the plex server was gone.  
Trying to reinstall everything but now every video I play I get the error error code: h4 (not supported).

I have also added music but after scanning it is not added to my library.

When I open the details of a video it says  
Video None  
Audio None

when I unmatch the video it says

Video 1080p (HEVC Main 10)  
Audio English (EAC3 5.1)

Then when i re-match the file the codec information stays and I can olay the file.

However it’s to tedious to do this with every file by hand  
Whats the best aproach to fix this automaticly?

I seem to have a similar problem as mentioned here  
[https://www.reddit.com/r/PleX/comments/15r16cy/media\_not\_playable\_when\_added\_missing\_media/](https://www.reddit.com/r/PleX/comments/15r16cy/media_not_playable_when_added_missing_media/)

the plex agent doesnt seem too get the correct media info of the files in the library and playback of files fails. If I use an external player like vlc the file plays fine

Ive tried the solutions mentioned in the link above. (the [plex dance](https://forums.plex.tv/t/the-plex-dance/197064)) tried reinstalling pms, I even tried roolling back to a previous version.

I believe my probleem lies somewhere on the cloud. Can someone from plex reset my account so I could do a complete fresh reinstall?
