Hi pavelman.
Not mush information , but looking at your config.ini your "Select output folder" is wrong and also your "Select GGLoader temporary Folder" is wrong,
Could you try to follow the help file again step by step to ensure your folder selection is correct:
https://www.appgamekit.com/files/GameGuru%20Loader%20User%20Guide.pdf
If this dont help , could you provide a screenshot of your settings , and let me know the location of your AppGameKit project, ( where did you place the source code the "ggloader" folder ).
BTW: Your "Select your GG Loader folder" should point to where you installed the ggloader source code, i can also see that it do not do that in your config.ini.
It is supposed to convert ALL media , even media not in the entitybank , it will do this so all media is prepared and ready to use ( It will ONLY do this the first time you run it ) , so if you need a skybox/terrain texture ... later , they are already converted and ready to use , also some people are working on Mac/Linux so being able to copy everything to your Mac/Linux enable you to work on these system too.
