Setup problems

[GM-Pandora]

I never heard of different setup.exe, should be able to make it work with the one you got. The lightmap I'm not sure if the change is very visible, so I suggest you make your test with the full-screen checkbox.

Make sure you fully exited the game.
Make sure you are using setup.exe that is in the same RO folder where you have your heRO files installe. Default path should be (C:\Program Files\Gravity\RO)
Click ok when you're done of course.
