It would have been nice if someone at Plex could have included in the updater, that it could not install due to Mountain Lion being required, instead it over wrote my Plex server 9.16.6 version of plex with a version that will not run on my Macintosh. The only backup I had was Plex Server 9.15.6, which got me up and running again.
Is there anyway to get the last version that did run on Snow Leopard?
