Plex has stopped working at all. No subtitles neither metadata.

Everything has always worked fine for me, since the last Plex update. Now it doesn’t recognize any new movie or tv series, subtitles are not working. I`m posting some pics, just to show what is going on.

As you can see in the print screens, “The Flash” and “Rectify” are the Tv series that I recently downloaded, and both are not being recognized. It does play the episodes, but subtitles are not working and also the metadata.

Folders and files names are all just fine as well. My windows media player can play the episodes with subtitles.

Is there any way to downgrade Plex to an older version? Or is there any solution for this?
