That should no give a error. I work at my project at home at my desktop PC and also at my Laptop (Different folders). And i have never this problem. I have a folder that called "Dungeon" and in this floder are all my datas (Level, script, subfolders with Models, Bitmaps and so on). I can copy that folder to any place of my PC or Laptop and it works.

As i ask in my first post: Have you some #includes... at your script and how looks the code for that?
