Help: Error Message on Lost in the Nightmare Patch

[Bobcat]

I downloaded the Lost in the Nightmare patch into its game directory. I selected the game's folder to update, yet when I click "Next", an error message comes up saying that the game is an "unknown version". Could anyone make sense out of this for me? Has anyone else experienced an error like this?

Please contact the game's author. This is a problem with their custom patch system, and is not related to AGS.
