Atton Shield Glitch
 

Hey, so I've been getting this glitch where if I put a shield on Atton, his model goes weird (happens to the PC, but not as bad). Here's a video to show you: [Star Wars Knights Of The Old Republic 2] Atton Fail... - YouTube

Specs
Model: ASUS G73jh
Intel® Core™ i7 Processor 620M/820QM/720QM : 2.66 GHz - 1.6 GHz, with Turbo Boost up to 3.33/3.06/2.8 GHz;
OS: Windows 7
RAM: 4GB
Graphics Card: ATI Mobility™ Radeon® HD 5870, 1G GDDR5 VRA

That's pretty much it.
Help would be awesome, thanks!
