I have the same problem,Windows 8 with ATI Radeon HD 5850, when I start SSE Questviewer crashes. If I do a fresh re-install of windows 8, install SSE it works no problems. As soon as I install AMD Catalyst, with the latest Graphic drivers, Questviewer crashes...Very frustrating, since I usually play SSE on a 10 feet display(DLP projector) but I cannot use it, (hdmi port on the video card does not work until I install Catalyst), And after I install Catalyst, BAAAAAMMMMM! SSE crashes while loading questviewer....
I include my .dmp file.
That is not fun....
