Indeed the error message is fixed now.
About key binding, it's something else.
I've set PUIE to move, P being "forward". But ingame, each time i go forward, the equipment window opens/closes, as it seems P is hard binded to that. So, P has two distinct function, one i set manually (move forward), one i cannot remove (equipment window).
I didn't try every keys, but i suspect it's not the only one, so if you can look at that, i would be great.
