I don't understand "use it with maximum" :-(
To reset everything to default you can delete the file C:\Users\yourusername\AppData\Roaming\3DPixel\mkgi3DPixelV141.txt
I deleted the file that you mentioned but the program still doesn't open and I get the following error "An error occurred, please reinstall the application", any solution?
copyright issues solved, all is good now ;-)
