You can't just delete the game folder?
I opened all the folders Jenny & deleted the contents!
I've just done a search to see if there are any files left & discovered where the uninstall program had been hiding!

Any folders remaining are now empty!
.... I will never install this game again or anything else produced by the same developers......
An over-reaction on my part, I was tired & frustrated at the time! I may go back to it sometime in the future when I'm more in the mood to amble around.
