Whenever i try to start the game, a Bungie certificate pops up, demanding to access the game files. If I deny, the launch client will notify me that the game couldnt be started. If I accept. for a few second nothing will happen, followed by a second error pop up stating that the application is already running and the game wont start as well. I tried everything, cleaning the cache, redownloading steam and destiny but nothing would work... Does anyone know how to fix this? Edit: The program seems to change the file "cvars" causing problems... What can I do about that?
