I need help badly.
There is a crash error that has been bothering me for some time. Mid to late games on large or huge maps seem to crash when the game gets too 'big'. I have saved the DxDiag file and a screenshot of the error that always occurs.

I know my system is up to playing Civ 4. It has in the past.
PLEASE HELP!

Since this is with the Blue Marble mod, it's best to post in their thread. This forum is tech support for the unmodded version of the game.
