"Unable to open Z file" error

[wallace007]

When I try to open Arromanches battle, I get an error message which reads 'Unable to open Z file" and then the game shuts down. Advice anyone? I am running Windows XP.

I have the same error in War, for now just restart the game and the campaign goes on. [:)]

It is believed to associated with a virus scanner accessing the file at the same time.

as salhexe says just restart, no data is lost or other ill effects.
