Hi,
After a frustrating couple of hours of trying to set up plex on my system, and then finding just a load of gargled and quite useless information here, i can pretty much admit that punching my monitor (although painful) is a great idea!!
Im operating Windows 10 with plex downloaded to that, and my library is all formatted properly, yet when i click the my library option, i just keep getting the download plex server message, which has already been done!!!
All the setting’s are correct so im at a loss on why it does not work. Incidentally, i had the same issues when i tried setting it up early last year, decided it a waste of space and deleted it. Same is about to happen, so this is a last shout for help!!
