Hi again,
I installed the Itch.io app and installed RPGinABox on that and loaded up content from before, i exported again to save created folder (which only has 2 files, data.pck and game.launcher). Still same issue it starts with black screen with cursor- press spacebar and the map/level then will be visible, move to the stairs where i created a script link to the other map, walking into this just makes the screen go black and same error message as pointed out last time. Not sure what is going on. Any other suggestions?
