I think The setup.exe file should install common files like graal kindoms stuff like the ganis and gfx, or anything associated with the introduction of the game.
I reinstalled graal and went on there and started my character. Stuff was downloading all over the place and it was very confusing. The ship that you start near wasnt even there. People were talking, but their bodies werent there.
Im not sure if any of the classic ganis are installed with the client, but those would be a good idea too. Maybe some common Zone files like their intro GFX.
