Video codecs are the problem that causes the throne room advisor and the emissaries to crash. Have you installed any unusual ones? These might have been installed by some other programs you have. This is all covered in the thread I linked. I can't help you much beyond that as I haven't used windows for more than 12 months. If this problem persists I advise you to go to the .com and post a thread there, linking to this one. Maeda Toshiie is admin there and knows a lot about these kinds of problems.
