Sorry, it does not appear to be a bug, its some incompatiblity with your system by the look of it. I am pretty sure its not directly related to the upgrade. I dont know if this helps, but GameEx is failing when its trying to blit in directdraw 'errordialog.bmp'. You could possibly take a look at that graphics file. As I said I see no bug anywhere, or anything to do with something that has changed with the latest versions. How much RAM do you have? You could try setting the 16-bit colour setting, or trying a different graphics drivers. There has been reported issues with newer Nvidia drivers. Tom.
