For the time being, the company has decided to offer a “fix it yourself” guide for the Look/Spin/Stuck Key issue. It’s only a temporary fix, Rockstar warns, but it will restore Keyboard/Mouse and XInput (360) controller functionality.
A1) Unplug any DirectInput controllers (gamepads, joysticks etc..)
A2) Reboot your computer
A3) Launch GTA IV
However, should the issue still persist, users should follow the following instructions: and delete the conflicting DirectInput drivers:
B1) Exit game
B2) Go to Start->Control Panel->System->Hardware Tab->Device Manager->Human Interface Devices
B3) Locate drivers for devices
B4) Delete drivers for devices
B5) Launch GTA IV
Rockstar, how about a new patch? You know, one that actually works?
