When I launch GalCiv II, the intro movie is played, and then a dialog box appears with the message "There is no disk in the drive. Please insert a disk into drive ." (i.e. without giving a drive letter). All the buttons "Cancel", "Retry", "Continue" just makes the same error message appear, forcing me to close GalCiv the hard way. This happens only after I have installed any of the updates. The debug.err file gives no error messages.
Anyone have any idea what's wrong?
