i tried to install the mod, but after some failures i gave up the attempt, got rid of the the files and reinstalled the games vanilla campaign files but now the game crashes at the load screen
Maybe try deleting the napoleon game file then delete the custom script then reinstall.
http://www.twcenter.net/forums/showthread.php?t=396175 It's not updated, but it shows you the file that aren't vanilla (NOTE: the new patch5 & patch6.pack are shown as NON VANILLA FILES, but don't delete them!).
