[bug] Freezing cutscene?

After fighting a boss battle in Redcliffe castle, the game freezes during a cutscene after it. My questlog updates after defeating him, and during dialogue, the game freezes. I can open my local map, go into my character menu, inventory, etc. No dialogue pops up, however, and I can't do a thing about it! Has anyone else encountered this problem?

Specs are as follows:

Intel i7 @ 1.73 GHz

6.00 GB RAM

Nvidia GTX 460M

Windows 7

And before you ask, yes, I have the latest drivers for my graphics card and directX installed.
