How do I get an update for this now ? After buying it and trying it it gives an error message: Assets\FootstepSystem\Editor\FootstepSoundManagerWindow.cs(10,43): error CS0246: The type or namespace name 'ExtendedEditorWindow' could not be found (are you missing a using directive or an assembly reference?) How do I fix it ? I'm using Unity.2020.3.20f1 btw

I’ve looked into this error and have pushed an update that prevents the crash. Thanks for the report! If you have any further suggestions / questions please let me know.
