Hello, i bought BG EE few days ago and discovered that my sound, difficulty and graphic settings does not save. Whenever i start the game, they are at default ones. Also not sure if its just visual bug, but when i load my savegame difficulty options are way off and cant be changed (cant do a screenshot sadly). I tried to search for solution, but with no luck.

Make sure that you have write permissions for the folder
..\Documents\Baldur's Gate - Enhanced Edition\
The settings are stored in the file 'baldur.lua', so make sure that has not been set to read only.
