This error may occur if the ShortKeeper configuration file is corrupted. You can replace it (in your ShortKeeper folder) with the following default configuration file (if you don’t have a backup): ShortKeeper.exe.Config
You might have to reset some of the configuration options in ShortKeeper (e.g. "Start AutoHotkey with ShortKeeper", "Enable hotkeys to trigger shortcuts", "Display hotkey column in saved shortcuts") since the default configuration file will restore the options to their default settings.
