It may not be that bad, if you can elaborate on the differences between the two project files? Give me more details about what you've done and I'll see what I come up with.
The ability to import a ready to go project, but just add lights is a huge draw to some, for example i use the default Wolfmix project to open a new project file so that way there are a bunch of scenes pre-made ready to go, just need ot tweak to my needs.
