Game crashes when moving from the Nave to the Chancel

[gradford]

Yep, did all that, no change.

Actually, I did get into the Chancel prior to this problem. I ran around the rooms for quite a long session. I only did this once however. When I try to get back in the Chancel, I get the white light.

What's strange is that when I try and load up (or move into) the Chancel, there is a notable blip on the screen - the screen will flicker back and forth, like it's being turned off and turned back on again, and then I get the white light.

I don't know if this helps
