Okay so there are 2 item glitches i have encountered, i have seen people use the ring of hircine unlimited to times to become werewolf but when i use it, it says powers can only be used once a day (i have the ring equipped, and it wont work) The second is on a Dark brotherhood mission called Whispers In The Dark when you hide in the night mothers coffin the game just goes black i hear cicero (keeper/jester) walking towards it but then he never speaks, therefore i am stuck in the coffin+cant complete quest+have to reload a past save.

does anyone know how to fix these? please tell.
