The latest version of Subdued (188.8.131.52) consistently gives me the dreaded Invalid Application – Unable to launch “media browser” error.
I have uninstalled/reinstalled Media Browser, removed all themes and plugins except Subdued and CoverArt, removed all but one small library, and run a full manual refresh.
Revert back to version 184.108.40.206, and Media Browser will load. Upgrade to version 220.127.116.11 and Media Center will crash. I can consistently reproduce this by swapping the two versions of Subdued.

Not sure how the problem occurred in the first place, but swapping back and forth will definitely cause it to happen. When 2.4.1 starts up, it attempts to move all of the Subdued display prefs files from the Plugins/Configurations folder to Plugins/Configurations/SubduedDisplay. Problem is that 2.4.0 will continue to read/write its display prefs in the old location—which is why you may have noticed that your Subdued-specific view settings were reset when you went back to 2.4.0. If you would like to use 2.4.1, then first go to C:\ProgramData\MediaBrowser\Plugins\Configurations and manualy move any file that matches Subdued_*.xml to the SubduedDisplay subfolder. My guess is that you will find one that already exists in that location, which is causing the exception on startup. I will safeguard against this in the next release, but this should get you back up and running with 2.4.1.
