I have tried uninstalling Nvidia Experience and still same problem. I don't know what to do anymore :(
Does screen resolution or window mode / fullscreen mode contribute to this? But I've already tried using different game resolution and screen size
the very first time I started demonbuddy and game, it was successful (successful logging in and injected). Though it took demonbuddy like a good 3-4 mins logging in. I then tried to browse through some of the Demonbuddy settings to check them out but it was also extremely slow and unresponsive...
