I cannot elaborate further on anything other than the part that says “remove the script”, as I’ve already written the other parts as simple as I could. If you’re unable to remove something you installed yourself, all I’d tell you to do is to either remove/rename the t4 folder from %localappdata%\Plutonium\storage or uninstall/rename the entire Plutonium directory, then run the installer/updater. Consider renaming them instead of deleting them as they hold your installed mods, settings, and probably stats files.
