I have no mods in use, and I've beaten the game once. I tried to create a new character and all went well until it said "use capslock to run" so I tried that, but it didn't work. I got past the machine for setting your SPECIAL stats, but when the doc says to sit on the couch, I can't. It gives me the same sound effect when you try to hit the "use" button and there isn't anything to use. I can take items off of tables and cabinets and such, but using the same button, I cannot sit on the couch to continue the game.
I've even tried remapping, restarting my computer, and creating a new save file, with no effect. Any help?
