Trainz 2004 de luxe editionv2.2 build 2283

On certain sections of Trainz, i.e. Scenarios,Driver and Surveyor ( all other sections work normally} a Fatal Error message is displayed. It reads as follows:

Class: Hardware
Reason: Access Violation

C:\WINDOWS\system32\sisgl.dll

This problem happens with both OpenGL & DirectX9c

This could be a problem with the game itself (check if there is a patch for the game) or the display driver.

Unfortunatly SiS has a long history of buggy and unstable drivers, you could check if SiS offers a newer driver though.
