Is that the dialogue where you pick a room?
What options did you choose there, and when it crashes, does it have an error box pop up?
i think i just got a bad download, deleted and re-installed and it works fine now. however yes. it was the last dialogue before sleeping into the next day. before that, I had entered the event and was ready to begin playin
Only thing I can think of is possibly a graphic driver issue, though who knows why it would crash it during dialog.
