As the title says, whenever I come within speaking range of the contact in the steam room in the Vegas strip casino with the White Gloves (can't remember the name), my game locks up and I have to use the task manager to terminate the program. I can't proceed with the quest, and have repeated this crash several times.

Anyone else having similar issues, or have a solution to this problem?

If there's some information I'm forgetting to add to make responding easier, by all means let me know, I'm still stuck here.
