I can look around, but I can't jump, I can't attack and I can't switch from third-to first person. I brawled with Vilkas at Jorrvaskr to prove my worth for the Companions, and when I left dialogue, I couldn't move.
I can't open any menus, except for settings, and quest. I tried quicksaving and reloading, and I tried restarting, but neither worked. Can I get some help? I'm playing on a laptop PC.
