Has anyone run into issues with: Failed to load extension from c:/[gamefolder here]. Manifest file is missing or unreadable. I updated 1.6.1, using Yanfly's newest desktop optimization module. Otherwise followed instructions. Game ran fine before. How odd! Suddenly, NO RPG Maker game will run. I get the same error. I should say Playtesting doesn't work. Running a compiled game seems to work ok. Hmm, moving back to 1.5.2 fixes the issue. Odd indeed.
