I am currently having the same issue. WASD doesn't work along with most buttons attached to the keyboard like stances, inventory and other general keys. The weird thing is that some buttons work like the spacebar, the arrow keys for movement, the numpad and my mouse. This issue happens in both singleplayer and multiplayer. I have also verified my files on steam and nothing is missing. I have also checked all the ingame settings and the key mappings to the keys exist, but they just don't want to work and I can't remap the the keys that don't work. The game acts like it doesn't detect them being pushed.
