Beast Form broken somehow?

[AerintheGREAT]

Beast Form simply isn't working correctly for me and I'm unable to find a solution. I will describe the problem (bear with me) and what how I've tried to fix it so far...

What Happens:
Selecting the Beast Form shout/power and using it causes the werewolf model to appear 'around' my player character model, but the camera does not transition to 3rd person and display the transformation animation/sound effect/etc. However, if you switch to 3rd person before using Beast Form you can see the animation, but there is no sound and the player model is still visibly being 'overlapped' by the werewolf model.
Once the werewolf model has appeared fully there are two distinct behaviors that occur and neither are correct.
If you are in 1st person, then the view is obstructed by the inside of the werewolf models' snout and hair, but you can still see that the players hands are still using weapons/magic underneath the werewolf claw models. The player can still run around and attack things and loot bodies etc. but the werewolf model never goes away and has no effect on stats or anything... it is simply an annoying obstruction of your view.
When you switch to 3rd person, suddenly nothing works except for mouselook control of the camera and a 'jump' of sorts that does not actually produce a jump animation. The player is unable to move or do anything at all and the werewolf model is seen to be holding the players currently equipped weapons/spells. The player character model is still visibly 'underneath' the werewolf model as well.

What I've Tried:
I've verified the game cache. I've deactivated all mods. Nothing has any effect. I'd really rather not fully uninstall and have to reinstall everything on my currently crap internet connection... But it feels inevitable at this point...

I just want to know if anybody else has had this problem before and if there is a solution. After some googling I found a few similiar descriptions of other werewolf glitches, but none with solutions and none exactly as I've experienced anyways.

Any help or suggestions would be greatly appreciated. Thanks for your time if you've read this far :-P

NOTE: For some screenshots illustrating the problem, see my accounts latest Skyrim screenshots

Some mods save their data into the save file (even skyrim cannot remove their code), so you will need to start a new game. Try not to use those types of mods as once the author release buggy version of their mod, chances are your save is screwed. Even updating the mod would make the problem persist.

Hrmm... I don't recall ever installing a mod that effected the player character's werewolf transformations or anything like that... though I suppose I could have forgotten. I'll check that then. It'd suck to lose progress, but I guess I was going to eventually start a new primary anyways...

Regardless, thanks for the input. I'll have to look into what I might have installed previously...
