Hi, I've just bought divine divinity (a replay version) and I have a problem at the very beginning. After the first 2 rooms there is a ladder to go up. I click on the ladder and the music changes, my character disappears but the scenery remains the same (ie I can still only see those 2 rooms). I can click on any menus, inventory, etc no problem but can't control my character as it has disappeared. Help!
