Crashing problems after cut scene

The only time I've experienced this issue is after I installed the game on a far more capable computer with a better graphics card and changed my settings for the game's graphics.  I selected for it to use the High Quality textures, and suddenly I kept getting crashes to desktop.  I spent days running the problem down and trying to beat it into submission, and FINALLY discovered that the problem was the High Texture files were having problems due to a corrupt file.  I reinstalled the texture files, reapplied the latest patch, and the crashes stopped.  I don't know if that will help your situation, but I'll keep my fingers crossed for you.
