I did another mp uninstall and cleanup on the one computer, and a clean install.
I installed fanart handler and tried to start mp windowed.
MP froze up at the plugin startup with a windows error but it is behind the mp splash screen so cannot be read.
mediainfo.dll is there in program files (86) last modified Dec, 10, 2020.
All of these plugins were up to date and working fine before i updated from MP 1.26 to MP 1.27.
The MP client on the TV server works fine with these plugins after the update.
The clients on the other 2 computers both started crashing after the update.
I hope I posted this in the correct Forum. I'm successfully running MP 1.25, FanArt Handler 4.03.304, PureVision 10.1.0.0, Holliday 1.0.0.5. I turned on Enable FanArt Holidays in the theme using Basic Editor). The Holidays FanArt working successfully with Theme SmartOne with the one line...
Replaced the FanartHandler.dll in the other computer and put the 3 FanartHandler.dbs in a backup folder.
Restarted the computer and it still crashes after a few seconds.
