I can't move my character or click menus.

I'm having troubles with my main character: it doesn't move no matter what I try.

I have switched the input method to WASD. That change lets me move the character, but I can't interact with anything or even attack.

The only skills that work are the ones bound to the keyboard's keys, the mouse's right button, and the mouse's wheel, but the game doesn't detect any action from the left button of the mouse.

It only happens with one character because I tried to use a new one, and everything works fine.

I tried to find a solution on different websites, but I can't find any solution. I have even verified the game's files, but it doesn't work.

Can anyone help me fix this? Thanks.

Edit: Forget about it, I have solved it switching skills on the left mouse's button.
