CTD

You will commonly see the abbreviation CTD used in the modding forums (and elsewhere) it means Crash to Desktop.

The Total War games load files in a pre-set order, so for loading crashes exactly when the CTD occurs can give a clue to what is wrong with your game.

Some CTD's give an error message if you are using the -show_err system in RTW/BI.

For some common causes of errors in RTW/BI see the modder's guide to errors at TWC and the modder's guide to CTD's at the .Org
