Plex Web App "There was a problem playing this item"
So I have 3 computers, on two of them I can play everything just fine through the plex web app (https://www.plex.tv) but on my third computer every time I try to play a .mkv I get the error "There was a problem playing this item" even though these files work on the other two systems. This happens with both movie and TV shows. I installed VLC player on the computer just to make sure it wasn't the fact that the computer couldn't play the file. I looked at the logs but I can't make any sense of it whatsoever so if anyone out there could help I would greatly appreciate it.
