Game crashes during first map transition

[mickj16]

Hi all,
Could somebody please help with this problem.
I load the game up, talk to the guy in the torture room. Jump out of the window. Wander out into the square. Climb the ladder, drop down on the other side of the fence and head into the only open door. At this point I get a "loading" message which then dumps me out to the menu screen with no option to resume. Is this a system prob or am I going to the wrong place.
I have loaded the latest vid card and Via 4 in 1 drivers. My game IS a bought version.

Thanks in advance

System
Athlon xp 1600
Geforce 4 Ti4200 128mb
512mb
Win 98

Game crashes during first map transition *UPDATE*

Due to not being able to edit my own post I have just replied to it with more info. After the game dumps back to the menu screen, I try to reload the saved position, the game crashes and this error message appears on the desktop

"too many verts for a dynamic vertex buffer (112281>32768) tell a programmer to up VERTEX_BUFFER_SIZE"

Any ideas would be great.
