[Displays moving/disappearing and invisible walls in player homes]

So I downloaded Sjel Blad castle because its one of my all time favorite player homes, but when I tried to reenter it today my displays had been moved and there were invisible objects every where making it hard to move around. I thought it was a bug with Sjel Blad so I downloaded a new player home and reverted to a save before i had entered Sjel Blad, but it happened in this new player home too... Is this a known bug for skyrim and is there a fix?...

[Skyrim freezes if i click anything in pause menu.]

As the title says, I can not save, edit settings, or close game with out skyrim completely freezing.
