Hello i have installed the NVN 2 Complete from GOG. Still i have the problem with the keyboard controls. Not a single hotkey response to my need. Fortunately the mouse is working correctly, but is there anyone who had the same issue as i do .

First time I have heard anyone having that kind of problem. You're using the number keys and not the F keys right? (In the first NWN you used the F keys as hotkeys instead of the number keys)

In case you got a security suite running on your system, make sure the game's executable isn't running in sandbox mode! If that is what's causing your problem you either need to add an exception or simply run it as administrator. Sometimes other devices attached to your system can cause this problem. Most likely a controller or tablet.
