Oops! That'll be it then, looks like I missed a couple of files from the demo... I'm just emailing them to you now, once I know you're up and running I'll refresh the DEMO download.
It's a little concerning though when you say you don't have the first 5 files because they are created when you run the database rebuild... provided you are running the latest version of MakeRwys from the correct P3D folder?
